        Bug 54524 - Allow JSObject to fully utilize cell's capacity for inline storage.

        Currently JSObject is both directly instantiated for regular JS objects, and
        derived to implement subtypes. A consequence of this is that we need to ensure
        that sufficient space from the cell is left unused and available for any data
        members that will be introduced by subclasses of JSObject. By restructuring
        the internal storage array out of JSObject we can increase the size in the
        internal storage for regular objects.

        Add classes JSFinalObject and JSNonFinalObject. JSNonFinalObject retains as
        much additional capacity as is currently available to allow for data members
        in subclasses. JSFinalObject utilizes all available space for internal storage,
        and only allows construction through JSFinalObject::create().

        The additional storage made available in the JSObject means that we need no
        longer rely on a union of the internal storage with a pointer to storage that
        is only valid for external storage. This means we can go back to always having
        a valid pointer to property storage, regardless of whether this is internal or
        external. This simplifies some cases of access to the array from C code, and
        significantly simplifies JIT access, since repatching no longer needs to be
        able to change between a load of the storage pointer / a LEA of the internal
        storage.

        Refactor handles and weak pointers to become nicer and more automatic
        https://bugs.webkit.org/show_bug.cgi?id=54415

        Move to a true handle based mechanism for GC value protection.  This
        also allows us to switch to a more sensible behaviour for weak pointers
        in which weak pointers are automatically updated.

        This allows us to remove the old (and convoluted) that required all
        objects that may be held by a weak reference to be aware of the reference
        and manually clear them in their destructors.

        This also adds a few new data types to JSC that we use to efficiently
        allocate and return the underlying handle storage.

        This patch is largely renaming and removing now unnecessary destructors
        from objects.

        A little more encapsulation for the heap: Removed CollectorHeapIterator

        CollectorHeapIterator is a God object that knows the internals of each
        of the pieces of the heap. This undermines the encapsulation I'm trying
        to achieve by splitting concepts into different classes.
        
        As an alternative, I've given each class a forEach iteration function,
        which takes a functor as an argument. Now, each class just needs to
        know how to iterate the things it knows about.

        will happen on. It was difficult to manipulate this in a subclass because
        the current DefaultGCActivityCallback class does this in its constructor.
        This patch generalizes things a bit more so that a specific run loop can

        can stay in DefaultGCActivityCallback and a subclass can specify any runloop.

        is guaranteed to outlast any GC-owned data structure. The heap is also

        the heap is responsible for marking all roots.

        This is simpler, and it avoids destructor-time access between garbage

        (JSC::MarkedSpace::destroy): Make sure to clear mark bits before tearing

        Skipping forward upon construction was causing the heap to skip running
        the destructor for the very first object in a block when destroying the
        block. This usually did not crash, since block destruction is rare and
        most objects have pretty trivial destructors. However, in the rare case
        when the heap would destroy a block whose first object was a global
        object or a DOM node, BOOM.

        generate a ldr r8,[r1, #7] which isn't valid on ARMv5 and lower.
        The intended instruction really is ldrb r8,[r1, #7]; ensure we
        call load8 instead of load32.

        Bogus callframe during stack unwinding
        https://bugs.webkit.org/show_bug.cgi?id=53454

        Trying to access a callframe's globalData after destroying its
        ScopeChain is not a good thing.  While we could access the
        globalData directly through the (known valid) scopechain we're
        holding on to, it feels fragile.  Instead we push the valid
        ScopeChain onto the callframe again to ensure that the callframe
        itself remains valid.

        The FixedVMPoolAllocator currently uses a best fix policy -

        Convert markstack to a slot visitor API
        https://bugs.webkit.org/show_bug.cgi?id=53219

        Move the MarkStack over to a slot based marking API.

        In order to avoiding aliasing concerns there are two new types
        that need to be used when holding on to JSValues and JSCell that
        need to be marked: WriteBarrier and DeprecatedPtr.  WriteBarrier
        is expected to be used for any JSValue or Cell that's lifetime and
        marking is controlled by another GC object.  DeprecatedPtr is used
        for any value that we need to rework ownership for.

        The change over to this model has produced a large amount of
        code changes, but they are mostly mechanical (forwarding JSGlobalData,
        etc).

        [jsfunfuzz] parser doesn't enforce continue restrictions correctly.

        This patch reworks handling of break, continue and label statements
        to correctly handle all the valid and invalid cases.  Previously certain
        errors would be missed by the parser in strict mode, but the bytecode 
        generator needed to handle those cases for non-strict code so nothing
        failed, it simply became non-standard behaviour.

        Now that we treat break and continue errors as early faults in non-strict
        mode as well that safety net has been removed so the parser bugs result in
        crashes at codegen time.

        JIT requires VM overcommit (particularly on x86-64), Linux does not by default support this without swap?

        The FixedVMPool Allocator does not work well on systems where
        allocating very large amounts of memory upfront is not reasonable,
        like Linux without overcommit enabled. As a workaround, on Linux,
        default to the values used in embedded environments (in the MB
        range), and only jump to the GB range if we detect at runtime that
        overcommit is enabled. Should fix crashes on Linux/x86_64 with

        Bug 52079 - Syntax errors should be early errors.

        From chapter 16 the spec:
            An implementation must report most errors at the time the relevant ECMAScript language construct is
            evaluated. An early error is an error that can be detected and reported prior to the evaluation of
            any construct in the Program containing the error. An implementation must report early errors in a
            Program prior to the first evaluation of that Program. Early errors in eval code are reported at
            the time eval is called but prior to evaluation of any construct within the eval code. All errors
            that are not early errors are runtime errors.

            An implementation must treat any instance of the following kinds of errors as an early error:
                * Any syntax error."

        Bug 52035 - Unregistering DOMWrapperWorlds is unsafe

        The method DOMWrapperWorld::unregisterWorld() effectively calls the DOMWrapperWorld's
        destructor early, in order to release wrappers once we know we no longer intend to use them.
        Whilst it is okay to have a method to throw away wrappers (assuming we know we're willing to
        lose any state stored on them) it is not okay to deregister the world from the JSGlobalData.
        A sequence of events that triggers the bug would look like this:

        (1) Create a DOMWrapperWorld.
        (2) Register a timer in the world.
        (3) Call unregisterWorld() on the world.
        (4) Timer goes off, code is executed in the world, creates a Node not attached to a Document.
        (5) We attempt to lookup a wrapper map for the world on the JSGlobalData, but because we've
            called forgetWorld() none exists.
        (6) Attempt to add a wrapper to a NULL map.

        Fix the problem by not removing the JSGlobalData's wrapper map until the world really goes away.

        double (rather than an integer immediate).

        <rdar://problem/8241425> JIT executable memory excessive usage due to regex caching
        https://bugs.webkit.org/show_bug.cgi?id=51434

        Reduce the amount of memory the RegExpCache can hold on to on iOS.
        Currently the RegExpCache can hold 256 RegExp objects. If each falls into a separate
        ExecutablePool, with a common size of 16Kb, this means we end up holding onto 4Mb of
        memory. Firstly, we can reduce this by simply reducing the size of the cache to 32
        entries. Secondly, we can use a separate set of ExecutablePools for JIT code generated
        from RegExp objects. This helps in two ways (1) it increases the probability that
        RegExps in the cache share the same pool, and (2) it means that a RegExp can't end
        up holding on to a large ExecutablePool containing a translation of JS code.
        (A RegExp could end up keeping a larger RegExp alive that happened to be sharing the
        same pool, but large RegExp patterns are less common).

        This problem was caused by having a parameter named 'arguments'.

        Bug 51358 - Should check stack depth rather than using recursion limits in byte compilation

        The current implementation of recursion limit checking is not safe on smaller stacks.
        Switch to using a common mechanism, shared with the parser, to check recursion limits.

        Make bytecompiler use StackBounds. Empirical testing shows emitStrcat to have the largest
        footprint on the stack, at just under 1k on x86-64.  Given this, the default recursion
        check (requiring 4k of available space to recurse) seems reasonable.

        Bug 26276 - Need a mechanism to determine stack extent

        This patch adds a class 'StackBounds', to hold information about the machine stack.
        The implementation of this class broadly adheres to the current implmentation of
        stack limit checking, and as such does not solve the problem of determining stack
        extent, but gives us a common place to do so.

        Currently two mechanism are provided to determine the stack origin (the point the
        stack is growing away from). currentThreadStackBase() in Collector provides a
        more accurate determination of the stack origin, so use this to calculate
        StackBounds::m_origin; WTFThreadData::approximatedStackStart is less accurate, and
        as such can be removed.  Cache the StackBounds on WTFThreadData such that they
        need only be determined once per thread, and for non-API contexts cache this
        information in JSGlobalData, to save a thread-specific access.

        For the time being retain the estimate of stack size used by JSC's parser
        (128 * sizeof(void*) * 1024), with a view to replacing this with something more
        accurate in the near future.

        Incorrect logic for returning memory at the end of linking.
        Reviewed by Geoff Garen.

        At the end of linking we return any space at the end of the
        allocated executable region that was saved due to branch
        compaction.  This is currently by done by subtracting the
        different from the m_freePtr in the allocation pool.  This
        can be incorrect if your allocation was made from a new
        page that was not selected for subsequent allocations.

        This patch corrects this behaviour by verifying that the
        memory being returned actually comes from the current
        allocation pool.

        - Allow backtracks to be direct via an indirect branch for an address

        - Propogate backtracks instead of adding trampolines.  Backtracks are
          propogated to where they are used.  This change also eliminated 
          trampoline branch code that aren't used.
        - Added global expression state to keep track of parentheses tail
          code and indirect branches.
        Other changes made to support these changes.
        - Split invertOrCapture flag on Patterns to two separate flags.  Added
          getters for these flags.  Rippled these changes to both the JIT 
          and interpreter code.
        - Split BacktrackDestination out off TermGenerationState struct.
          This is done to hold references to a backtrack for later code
          generation.

        Bug 50298 - /()()()()()()()()()(?:(\10a|b)(X|Y))+/.exec("bXXaYYaY") ASSERTs

        For unmatched subpattens we previously used to set the subpattern end to -1,
        but now we only set the start value. E.g. consider the following:
            /a(b)?c/.exec("ac");
        Previously we would generate an internal results array of:
            [ 0, 2, -1, -1 ]
        Since fairly recently we have generated results of:
            [ 0, 2, -1, ??? ]
        (With the end index of the subpattern uninitialized).

        Update these ASSERTs to account for this.

        Also, when stripping out self-referencing backreferences, (e.g. /(\1)/) we
        were checking the wrong property on the pattern term. We should have been
        looking at term.parentheses.subpatternId, but instead were checking
        term.subpatternId. The latter is actually only the subpatternId for
        back reference terms. Rename this to backReferenceSubpatternId.

        Bug 48101 - Yarr gives different results for /(?:a*?){2,}/

        The test cases in the linked mozilla bug demonstrate a couple of
        problems in subpattern matching. These bugs lie in the optimized
        cases - for matching parentheses with a quantity count of 1, and
        for matching greedy quantified parentheses at the end of a regex
        (which do not backtrack).

        In both of these cases we are failing to correctly handle empty
        matches. In the case of parentheses-single matches (quantity count
        one) we are failing to test for empty matches at all. In the case
        of terminal subpattern matches we do currently check, however there
        is a subtler bug here too. In the case of an empty match we will
        presently immediately fall through to the next alternative (or
        complete the regex match), whereas upon a failed match we should
        be backtracking into the failing alternative, to give it a chance
        to match further (e.g. consider /a??b?|a/.exec("ab") - upon first
        attempting to match the first alternative this will match the empty
        string - since a?? is non-greedy, however rather than moving on to
        the second alternative we should be re-matching the first one, at
        which point the non-greedy a?? will match, and as such the result
        should be "ab", not "a").

        Terminal subpattern matching contains a second bug, too. The frame
        location values in the subpattern should be being allocated with
        the outer disjunction's frame (as we do for the parentheses-single
        optimization). Consider the following three regexes:
            /a*(?:b*)*c*/
            /a*(?:b*)c*/
            /a*(?:b*)*/
        Considering only the frame location required by the atoms a,b, and
        c, (ignoring space associated with the nested subpattern) the first
        regex (a normal subpattern match) requires a frame size of 2 for
        the outer disjunction, (to backtrack terms a & c), with each
        iteration of the subpattern requiring a frame of size 1 (in order
        to backtrack b). In the case of the second regex (where the
        parentheses-single optimization will kick in) the outer frame must
        be set up with a frame size of 3, since the outer frame will also
        be used when running the nested subpattern. We will currently only
        allocate a farme of size 1 for the outer disjuntion (to contain a),
        howver the frame size should be 2 (since the subpattern will be
        evaluated in the outer frame). In addition to failing to allocate
        frame space the frame offsets are also presently invalid - in the
        case of the last regex b's frame location will be set assuming it
        to be the first term in the frame, whereas in this case b lies
        after the term a, and should be taking a separate frame location.

        In order to correctly allocate the frame for terminal subpattern
        matches we must move this optimization back up from the JIT into
        the compiler (and thus interpreter too), since this is where the
        frame allocation takes place.

        [GTK] Optimize foldCase, toLower and toUpper methods in glib unicode backend
        https://bugs.webkit.org/show_bug.cgi?id=48625

        GLib methods use UTF-8 strings, so we have to convert from UTF-16 to
        UTF-8 to perform the case operations and then convert back the result to
        UTF-16. GLib conversion methods return a new allocated string, so we
        have to memcpy the result into the destination buffer too. Using our
        own methods to convert between UTF-8 and UTF-16 from wtf/unicode/UTF8.h
        we don't need such memcpy, since they take an already allocated buffer
        rather than returning a new one. There's another optimization for the
        case when the destination buffer is not large enough. In that case,
        methods should return the expected destination buffer size and are

        Use paths relative to $WebKitVSPropsRedirectionDir to access shared .vsprops files

        Apple's Windows build allows placing header files and import libraries for WebKit's
        dependencies (CoreGraphics, CFNetwork, SQLite, etc.) outside the source tree via the
        $WebKitLibrariesDir environment variable. This is both required for production builds and
        convenient for Apple-internal developer builds. Apple's production builds also require that
        WebKit's shared .vsprops files be accessed relative to $WebKitLibrariesDir. In production
        builds, the files are copied into that directory tree by the
        WebKitLibraries/win/tools/WinTools.make file. In Apple-internal developer builds, the
        copying is done by
        JavaScriptCore/JavaScriptCore.vcproj/JavaScriptCore/JavaScriptCoreGenerated.make.

        This .vsprops copying is problematic in one very important case: when a developer updates
        their source tree and then tries to build. Visual Studio only reads .vsprops files when a
        project is first loaded. So, when Visual Studio is first opened after the .vsprops files are
        updated, it reads in the old files that were already residing in $WebKitLibrariesDir. When a
        build is started, JavaScriptCoreGenerated.make copies the new .vsprops files into
        $WebKitLibrariesDir, but Visual Studio will not pick up the changes.  The rest of the build
        will proceed with out-of-date .vsprops files, which will likely result in a build failure.

        To fix this, we now use normal relative paths to access the .vsprops files in the source
        tree rather than in $WebKitLibrariesDir, but prefix those paths with a new environment
        variable, $WebKitVSPropsRedirectionDir. In developer builds, this environment variable is
        unset, so the normal relative paths are used to read the .vsprops files out of the source
        tree directly. In production builds, this environment variable is set to a fake directory
        that will cause the .vsprops files in $WebKitLibrariesDir to be found when the relative path
        is resolved.
        
        For example, JavaScriptCore.vcproj uses this path for FeatureDefines.vsprops:

        $(WebKitVSPropsRedirectionDir)..\..\..\WebKitLibraries\win\tools\vsprops\FeatureDefines.vsprops

        In developer builds, where $WebKitVSPropsRedirectionDir is unset, this will point to the
        files in WebKitLibraries\win\tools\vsprops in the source tree. In production builds,
        JavaScriptCore.make sets $WebKitVSPropsRedirectionDir to
        "$(SRCROOT)\AppleInternal\tools\vsprops\OpenSource\1\2\3\", so the full path for
        FeatureDefines.vsprops becomes:

        $(SRCROOT)\AppleInternal\tools\vsprops\OpenSource\1\2\3\..\..\..\WebKitLibraries\win\tools\vsprops\FeatureDefines.vsprops

        which resolves to:

        $(SRCROOT)\AppleInternal\tools\vsprops\OpenSource\WebKitLibraries\win\tools\vsprops\FeatureDefines.vsprops

        (We rely on the fact that Windows doesn't care whether the directories "1", "2", and "3"
        actually exist since they are matched by an equal number of ".." path components.)

        Note that Visual Studio still won't pick up changes made to .vsprops files while Visual
        Studio is open, but that problem hasn't seemed to cause developers many headaches so far.

        Bug 49635 - Profiler implementation is fragile

        The profile presently requires the exception handling mechanism to explicitly
        remove all stack frames that are exited during the exception unwind mechanism.
        This is fragile in a number of ways:
          * We have to change bytecode register allocation when compiling code to run
            when profiling, to preserve the callee function (this is also required to
            call did_call after the call has returned).
          * In the JIT we have to maintain additional data structures
            (CodeBlock::RareData::m_functionRegisterInfos) to map back to the register
            containing the callee.
          * In the interpreter we use 'magic values' to offset into the instruction
            stream to rediscover the register containing the function.

        Instead, move profiling into the head and tail of functions.
          * This correctly accounts the cost of the call itself to the caller.
          * This allows us to access the callee function object from the callframe.
          * This means that at the point a call is made we can track the stack depth
            on the ProfileNode.
          * When unwinding we can simply report the depth at which the exception is
            being handled - all call frames above this level are freed.

        Bug 49635 - Profiler implementation is fragile

        The profile presently requires the exception handling mechanism to explicitly
        remove all stack frames that are exited during the exception unwind mechanism.
        This is fragile in a number of ways:
          * We have to change bytecode register allocation when compiling code to run
            when profiling, to preserve the callee function (this is also required to
            call did_call after the call has returned).
          * In the JIT we have to maintain additional data structures
            (CodeBlock::RareData::m_functionRegisterInfos) to map back to the register
            containing the callee.
          * In the interpreter we use 'magic values' to offset into the instruction
            stream to rediscover the register containing the function.

        Instead, move profiling into the head and tail of functions.
          * This correctly accounts the cost of the call itself to the caller.
          * This allows us to access the callee function object from the callframe.
          * This means that at the point a call is made we can track the stack depth
            on the ProfileNode.
          * When unwinding we can simply report the depth at which the exception is
            being handled - all call frames above this level are freed.

        The bug here is that we read the prototype from the RHS argument using a regular
        op_get_by_id before op_instanceof has checked that this is an object implementing
        HasInstance. This incorrect behaviour gives rise to further unnecessary complexity
        in the code base, since we have additional logic (implemented using the
        GetByIdExceptionInfo data structures on CodeBlock) to convert not an object errors
        from the get_by_id into invalid parameter errors. Having fixed this bug this code
        is all redundant, since in these cases the get_by_id will never have been reached.

        Bug 49577 - Function.prototype should be non-configurable

        JSC lazily allocates the prototype property of Function objects.

        We check the prototype exists on 'get', but not on 'put'.
        If you 'put' without having first done a 'get' you can end up with a configurable
        prototype (prototype should only ever be non-configurable).

        This is visible in a couple of ways:
          * 'delete' on the property may succeed. (the next access will result in a new,
          reset prototype object).
          * the prototype may be set to a getter.

        Bug 49488 - Only add source specific information to exceptions in Interpreter::throwException

        Three types of source location information are added to errors.

        (1) Divot information.

        This was added with the intention of using it to provide better source highlighting in the inspector.
        We may still want to do so, but we probably should not be exposing these values in a manner visible to
        user scripts – only through an internal C++ interface. The code adding divot properties to objects has
        been removed.

        (2) Line number information.

        Line number information is presently sometimes added at the point the exception is created, and sometimes
        added at the point the exception passes through throwException. Change this so that throwException has
        the sole responsibility for adding line number and source file information.

        (3) Source snippets in the message of certain type errors (e.g. 'doc' in `Result of expression 'doc' [undefined] is not an object.`).

        These messages are currently created at the point the exceptions is raised. Instead reformat the message
        such that the source snippet is located at the end (`Result of expression 'b1' [undefined] is not an object.`
        becomes `'undefined' is not an object (evaluating 'b1.property')`), and append these to the message at
        the in throw Exception. This presents a number of advantages:
          * we no longer need to have source location information to create these TypeErrors.
          * we can chose to append source location information in other error messages, including those where
            passing source location to the point of construction would be inconvenient.
          * we can chose in future to omit to append source location information when running in a non-debug mode.

        This also cleans up some error output, e.g. removing double brackets ('[[]]') around objects in output,
        removing double periods (..) at end of lines, and adding slightly more context to some errors.

        Bug 49420 - Clean up syntax/reference error throw.

        Some errors detected at compile time are thrown at runtime. We currently do so using a op_new_error/op_throw bytecode pair.
        This is not ideal. op_throw is used for explicit user throw statements, and has different requirements in terms or meta data
        attached to the exception (controlled by the explicitThrow parameter passed to Interpreter::throwException). To work around
        this, op_new_error has to add the meta data at an early stage, which is unlike other VM exceptions being raised.

        We can simplify this and bring into line with other exception behaviour by changing new_error from just allocating an
        Exception instance to also throwing it – but as a regular VM throw, correctly passing explicitThrow as false.

        REGRESSION: r69429-r69611: Crash in JSC::Interpreter::privateExecute
        https://bugs.webkit.org/show_bug.cgi?id=47573

        I think the interpreter portion of this was introduced by
        an incorrect but silent merge when I updated prior to committing.
        The JIT change is basically just a correctness fix, but it is
        needed to prevent the testcase from asserting in debug builds.

        The basic problem is incorrectly setting the activation object
        on an arguments object.  The crash was due to us setting a null
        activation in the interpreter, in the jit we were setting the
        activation of a strict mode arguments object.

        Bug 48365 - Remove output parameters from JITStackFrame

        The JIT stub functions presently use the stackframe to provide a couple of additional return values.
          * In the case of uncaught exceptions the exception value is returned on the stackframe.exception property.
          * In the case of caught exceptions the updated value for the callFrame register is returned on the stackframe.callFrame property.

        Change exception returns such that exceptions are always returned on JSGlobalData::exception.
        Change op_catch such that the new CallFrame value is returned from op_throw / vm_throw in regT0.

        Strict mode: Assignment that would create a global should be a late ReferenceError, not a syntax failure
        https://bugs.webkit.org/show_bug.cgi?id=47788

        Fixing this required a couple of changes:
         * resolve_base now has a flag to indicate whether it is being used for a put in strict mode.
           this allows us to throw an exception when we're doing a completely generic resolve for
           assignment, and that assignment would create a new global.
         * There is a new opcode 'op_ensure_property_exists' that is used to determine whether
           the property being assigned to already exists on the global object.  This currently
           has no caching, but such caching could be added relatively trivially.  It is only used
           in the case where we know that a property will be placed on the global object, and
           we cannot verify that the property already exists.

        In the jit we plant a call to cti_op_resolve_base_strict_put in the effected case rather
        than making op_resolve_base have an additional runtime branch.

        There's also a new helper function to create the exception for the invalid assignment.

        Automatic Semicolon Insertion incorrectly inserts semicolon after break, continue, and return followed by a newline
        https://bugs.webkit.org/show_bug.cgi?id=47762

        The old YACC parser depended on the lexer for some classes of semicolon insertion.
        The new parser handles ASI entirely on its own so when the lexer inserts a semicolon
        on its own the net result is a spurious semicolon in the input stream.  This can result
        in incorrect parsing in some cases:

        if (0)
            break
        ;else {}

        Would result in a parse failure as the output from the lexer is essentially

        if (0)
             break
        ;;else

        So the second semicolon is interpreted as a empty statement, which terminates the if,
        making the else an error.

        ARMv7 JIT should generated conditional branches when possible
        https://bugs.webkit.org/show_bug.cgi?id=47384

        Use different jump padding sizes for conditional and unconditional
        jumps (12 bytes and 10 bytes respectively). This allows the JIT to
        include the IT instruction as part of the conditional jump sequence
        which in turn allows it to optimize away the IT using an ARMv7 
        conditional branch instruction. Use 2-byte B(T1) and 4-byte B(T3) for
        conditional branches when displacement is in range. Also use IT/B(T4)
        for conditional branch when displacement does not fit in B(T3).

        For unconditional jump, instruction selection options are:
        B(T2), B(T4), MOVW/MOVT/BX. For conditional jump, instruction selection
        options are: B(T1), B(T3), IT/B(T4), ITTT/MOVW/MOVT/BX.

        Bug 43987 - Downloading using XHR is much slower than before
        Change StringBuilder to use overcapacity in a StringImpl, rather than a Vector.
        Fundamentally this should be the same (copies current contents to expand capacity,

        [ES5] Implement strict mode
        https://bugs.webkit.org/show_bug.cgi?id=10701

        Initial strict mode implementation.  This is the simplest
        implementation that could possibly work and adds (hopefully)
        all of the restrictions required by strict mode.  There are
        a number of inefficiencies, especially in the handling of
        arguments and eval as smart implementations would make this
        patch more complicated.  

        The SyntaxChecker AST builder has become somewhat more complex
        as strict mode does require more parse tree information to
        validate the syntax.

        Summary of major changes to the parser:
            * We track when we enter strict mode (this may come as a surprise)
            * Strict mode actually requires a degree of AST knowledge to validate
              so the SyntaxChecker now produces values that can be used to distinguish
              "node" types.
            * We now track variables that are written to.  We do this to
              statically identify writes to global properties that don't exist
              and abort at that point.  This should actually make it possible
              to optimise some other cases in the future but for now it's
              purely for validity checking.  Currently writes are only tracked
              in strict mode code.
            * Labels are now tracked as it is now a syntax error to jump to a label
              that does not exist (or to use break, continue, or return in a context
              where they would be invalid).

        Runtime changes:
            * In order to get correct hanlding of the Arguments object all
              strict mode functions that reference arguments create and tearoff
              the arguments object on entry.  This is not strictly necessary
              but was the least work necessary to get the correct behaviour.
            * PutPropertySlot now tracks whether it is being used for a strict
              mode write, and if so Object::put will throw when a write can't be
              completed.
            * StrictEvalActivation was added as an "activation" object for strict
              mode eval (so that strict eval does not introduce new variables into
              the containing scope).

        Lazily create activation objects
        https://bugs.webkit.org/show_bug.cgi?id=47107

        Make it possible to lazily create the activation object
        for a function that needs one.  This allows us to reduce
        the overhead of entering a function that may require
        an activation in some cases, but not always.

        This does make exception handling a little more complex as
        it's now necessary to verify that a callframes activation
        has been created, and create it if not, in all of the
        paths used in exception handling.

        We also need to add logic to check for the existence of
        the activation in the scoped_var opcodes, as well as
        op_ret, op_ret_object_or_this and op_tearoff_activation
        so that we can avoid creating an activation unnecesarily
        on function exit.

        Going forward, we'd like to get rid of the Noncopyable and FastAllocBase classes. The
        reason for this is that the Itanium C++ ABI states that no empty classes of the same type
        can be laid out at the same offset in the class. This can result in objects getting larger
        which leads to memory regressions. (One example of this is the String class which grew by
        sizeof(void*) when both its base class and its first member variable inherited indirectly
        from FastAllocBase).

        These methods implement the same conversion (see discussion in the notes

        is interpretted.

        Date prototype is incorrectly using toInt32, and this is causing us to
        provide an output value indicating whether the input to ToInt32 was finite
        (the corresponding methods on Date are actually spec'ed to use ToInteger,
        not ToInt32).  This patch partially fixes this in order to remove this
        bogus output value, hoewever more work will be require to bring Date

        Alternatives that begin with ^ are tagged during parsing
        and rolled up in containing sub expression structs.
        After parsing, a regular expression flagged as containing
        a ^ (a.k.a. BOL) is processed further in optimizeBOL().
        A copy of the disjunction is made excluding alternatives that
        are rooted with BOL.  The original alternatives are flagged
        to only be executed once.  The copy of the other alternatives are
        added to the original expression.
        In the case that all original alternatives are flagged, there
        won't be any looping alternatives.
        The JIT generator will emit code accordingly, executing the
        original alternatives once and then looping over the
        alternatives that aren't anchored with a BOL (if any).

        Imprecise tracking of variable capture leads to overly pessimistic creation of activations

        Both tests failed because Qt's implementation of String::format()

        Bug 44830 - In Array's prototype functyions we're incorrectly handing large index values

        We are in places casting doubles to unsigneds, and unsigneds to ints, without always check
        that the result is within bounds. This is problematic in the case of double-to-unsigned
        conversion because we should be saturating to array length.

        Also, the error return value from Array.splice should be [], not undefined.

        I don't see any security concerns here. These methods are spec'ed in such a way that they
        can be applied to non Array objects, so in all cases the (potentially bogus) indices are
        being passed to functions that will safely check accesses are within bounds.

        Bug 44745 - Number.toFixed/toExponential/toPrecision are inaccurate.

        These methods should be using a version of dtoa that can generate results accurate
        to the requested precision, whereas our version of dtoa is only currently able to
        support producing results sufficiently accurate to distinguish the value from any
        other IEEE-754 double precision number.

        This change has no impact on benchmarks we track.

        On microbenchmarks for these functions, this is a slight regression where a high
        precision is requested (dtoa now need to iterate further to generate a a greater
        number of digits), but with smaller precision values (hopefully more common) this
        improves performance, since it reduced the accurate of result dtoa is required,
        to produce, and removes the need to pre-round values before calling dtoa.

        [JSC] JavaScript parsing error when loading Equifax web page
        https://bugs.webkit.org/show_bug.cgi?id=42900

        '-->' is ostensibly only meant to occur when there is only
        whitespace preceeding it on the line.  However firefox treats
        multiline comments as a space character, so they are allowed.
        One side effect of the firefox model is that any line terminators
        inside the multiline comment are ignored, so

            foo/*
            */-->

        is treated as

            foo -->

        and so '-->' will not be a comment in this case.  Happily this simply
        means that to fix this issue all we need to do is stop updating
        m_atLineStart when handling multiline comments.

        Bug 44146 - Remove toDouble/toUInt32 methods from UString.

        These methods all implement JavaScript language specific behaviour, and as such
        are not suited to being on a generic string object.  They are also inefficient
        and incorrectly used, refactor & cleanup.  Uses of these methods really divide
        out into two cases.

        ToNumber:
        Uses of toDouble from JSString and from parseFloat are implementing ecma's
        ToNumber conversion from strings (see ecma-262 9.3.1), so UString::toDouble
        should largely just be moved out to a global jsToNumber function.  ToNumber is
        capable of recognizing either decimal or hexadecimal numbers, but parseFloat
        should only recognize decimal values.  This is currently handled by testing for
        hexadecimal before calling toDouble, which should unnecessary - instead we can
        just split out the two parts to the grammar into separate functions. Also,
        strtod recognizes a set of literals (nan, inf, and infinity - all with any
        capitalization) - which are not defined by any of the specs we are implementing.
        To handle this we need to perform additional work in toDouble to convert the
        unsupported cases of infinities back to NaNs.  Instead we should simply remove
        support for this literals from strtod.  This should provide a more desirable
        behaviour for all clients of strtod.

        Indexed properties:
        Uses of the toStrictUInt32 methods are were all converting property names to
        indices, and all uses of toUInt32 were incorrect; in all cases we should have
        been calling toUInt32.  This error results in some incorrect behaviour in the
        DOM (accessing property "0 " of a NodeList should fail; it currently does not).
        Move this method onto Identifier (our canonical property name), and make it
        always perform a strict conversion. Add a layout test to check NodeList does
        convert indexed property names correctly.

        Bug 44080 - String find/reverseFind methods need tidying up
        These methods have a couple of problems with their interface, and implementation.

        These methods take and int index, and return an int - however this is problematic
        since on 64-bit string indices may have a full 32-bit range.  This spills out into
        surrounding code, which unsafely casts string indices from unsigned to int. Code
        checking the result of these methods check for a mix of "== -1", "< 0", and
        "== notFound".  Clean this up by changing these methods to take an unsigned
        starting index, and return a size_t. with a failed match indicated by notFound.
        reverseFind also has a special meaning for the starting index argument, in that a
        negative index is interpreted as an offset back from the end of the string. Remove
        this functionality, in the (1!) case where it is used we should just calculate the
        offset by subtracting from the string's length.

        The implementation has a few problems too.  The code is not in webkit style, in
        using assorted abbreviations in variable names, and implementations of similar
        find methods with differing argument types were unnecessarily inconsistent. When
        find is passed const char* data the string would be handled as latin1 (zero
        extended to UTF-16) for all characters but the first; this is sign extended.
        Case-insensitive find is broken for unicode strings; the hashing optimization is
        not unicode safe, and could result in false negatives.

        Unify UString find methods to match String.

        Change UString constructors to match those in WTF::String.
        This changes behaviour of UString((char*)0) to create null
        strings, akin to UString() rather than UString::empty().
        (This matches String).  Remove unused constructors from
        UString, and add null-terminated UTF-16 constructor, to
        match String.  Move String's constructor into the .cpp to
        match UString.

        [Qt] Fix warnings: unknown conversion type character 'l' in format
        https://bugs.webkit.org/show_bug.cgi?id=43359

        Qt port doesn't call any printf in String::format(...), consequently
        using __attribute__((format(printf,m,n))) is incorrect and causes
        false positive warnings on Windows if you build with MinGW.

        Qt port calls QString::vsprintf(...) , which is platform

        Improve vsprops copying for Windows build
        https://bugs.webkit.org/show_bug.cgi?id=41982

        When we detect a new SDK, always copy a new set of vsprops files.
        Previously, if someone updated their SDK after updating their sources,
        they could end up with out-of-date vsprops files.

        Bug 43817 - Remove UString::Rep
        UString::Rep has for a long time been replaced by UStringImpl (Rep
        remaining as a typedef).  UStringImpl has since been removed too
        (unified with StringImpl). Remove Rep, rename rep() to impl() and
        m_rep to m_impl.  Also add impl() method to Identifier, and rename
        its UString member from _ustring to m_string.

        Allow an assembler/macroassembler to compact branches to more concise forms when linking
        https://bugs.webkit.org/show_bug.cgi?id=43745

        This patch makes it possible for an assembler to convert jumps into a different
        (presumably more efficient) form at link time.  Currently implemented in the
        ARMv7 JIT as that already had logic to delay linking of jumps until the end of
        compilation already.  The ARMv7 JIT chooses between either a 4 byte short jump
        or a full 32-bit offset (and rewrites ITTT instructions as appropriate), so does
        not yet produce the most compact form possible.  The general design of the linker
        should make it relatively simple to introduce new branch types with little effort,
        as the linker has no knowledge of the exact form of any of the branches.

        The JIT code contains a number of direct references to GC'd objects.

        in a code block, we can have the global object just be a member of the

        Bug 43515 - Fix small design issues with PageAllocation, split out PageReservation.

        The PageAllocation class has a number of issues:
        * Changes in bug #43269 accidentally switched SYMBIAN over to use malloc/free to allocate
          blocks of memory for the GC heap, instead of allocating RChunks.  Revert this change in
          behaviour.
        * In order for PageAllocation to work correctly on WinCE we should be decommitting memory
          before deallocating.  In order to simplify understanding the expected state at deallocate,
          split behaviour out into PageAllocation and PageReservation classes.  Require that all
          memory be decommitted before calling deallocate on a PageReservation, add asserts to
          enforce this.
        * add many missing asserts.
        * inline more functions.
        * remove ability to create sub-PageAllocations from an existing PageAllocations object -
          this presented an interface that would allow sub regions to be deallocated, which would
          not have provided expected behaviour.
        * remove writable/executable arguments to commit, this value can be cached at the point
          the memory is reserved.
        * remove writable/executable arguments to allocateAligned, protection other than RW is not
          supported.
        * add missing checks for overflow & failed allocation to mmap path through allocateAligned.

        Fix for https://bugs.webkit.org/show_bug.cgi?id=43314.  The prior code
        was using the wrong "length" value to move array contents when adding
        space to the beginning of an array for an unshift() or similar
        operation.  Instead of using m_vectorLength, the length of the
        allocated JSValue array, the code was using m_length, the declared

        Fixed a crash seen on the GTK 64bit buildbot.
        
        When JSArray is allocated for the vptr stealing hack, it's not allocated
        in the heap, so the JSArray constructor can't safely call Heap::heap().
        
        Since this was subtle enough to confuse smart people, I've changed JSArray
        to have an explicit vptr stealing constructor.

        Change to keep returned pointer from malloc family functions to
        quiet memory leak detect.  The pointer is saved in the new m_allocBase
        member of the ArrayStorage structure.  This fixes the issue found in 
        https://bugs.webkit.org/show_bug.cgi?id=43229.

        As part of this change, we use m_allocBase when reallocating and

        Changed the handling for removing and adding elements at the front
        of an array.  The code now keeps a bias that indicates the amount of
        JSValue sized holes are prior to the ArrayStorage block.  This means
        that shift operations are now memmove's of the header part of
        the ArrayStorage and unshift operations are similar, but may require a
        realloc first to create the space.  Similar operations are performed
        for special cases of splice and slice.
        Also optimized the new Array(size) case so that we don't allocate and
        initialize array elements until the JS code starts using elements.
        The array growth code is slightly more aggressive for initial growth
        based on size growth of any previous array.

        of an array.  The code now keeps a bias that indicates the amount of
        JSValue sized holes are prior to the ArrayStorage block.  This means
        that shift operations are now memmove's of the header part of
        the ArrayStorage and unshift operations are similar, but may require a
        realloc first to create the space.  Similar operations are performed
        for special cases of splice and slice.
        Also optimized the new Array(size) case so that we don't allocate and
        initialize array elements until the JS code starts using elements.
        The array growth code is slightly more aggressive for initial growth
        based on size growth of any previous array.

        Bug 43089 - Cleanup JIT related switched in Platform.h

        The code the enable to JIT checks every permutation of platform & OS individually, but
        now the JIT is enabled on the majority much all x86/x86-64/ARM/MIPS systems.  It should
        be cleaner to just enable by default on these platforms, and explicitly disable on configs
        that don't aren't supported.

        Also, rename ENABLE_JIT_OPTIMIZE_MOD to ENABLE_JIT_USE_SOFT_MODULO.  I always find this
        confusing since enabling this "optimization" would be possible, but would be a regression
        on x86/x86-64 systems!  I think it's clearer to reserve "JIT_OPTIMIZE" for compiler
        technologies applicable to all platforms, and make a more optional behaviour like this a
        "USE".

        WebKit on Windows should build optionally with an unversioned ICU DLL
        https://bugs.webkit.org/show_bug.cgi?id=42722
        <rdar://problem/8211743> JavaScriptCore needs to link against unversioned ICU
        
        Dynamically create a new header, ICUVersion.h, as part of build-generated-files.sh.
        Header contains a preprocessor define (U_DISABLE_RENAMING) indicating to ICU whether the ICU API
        should be namespaced with the current ICU version number. Proper value is determined
        by checking for the presence of libicuuc.lib, the unversioned copy of ICU.
        
        To get the proper value for U_DISABLE_RENAMING into all source files, we force
        the include of ICUVersion.h (our generated header) via the compiler options.

        Bug 42182 - Change how numeric compare functions are detected

        There are three problems with the current mechanism:
          * It requires that a function executable be bytecode compiled without
            being JIT generated (in order to copy the bytecode from the numeric
            compare function).  This is a problem since we have an invariant when
            running with the JIT that functions are never bytecode compiled without
            also being JIT generated (after checking the codeblock we assume the
            function has JIT code).  To help maintain this invariant 
          * This implementation will prevent us from experimenting with alternate
            compilation paths which do not compile via bytecode.
          * It doesn't work.  Functions passing more than two arguments will match
            if they are comparing their last two arguments, not the first two.
            Generally the mapping back from bytecode to semantics may be more
            complex then initially expected.

        REGRESSION: Crash at JSC::JIT::privateCompile(JSC::MacroAssemblerCodePtr*)

        There are two parts to this patch, the first is to fix the actual

        to contain BOMs we return a value indicating that there are no

        The getImm function is designed to produce modified immediate constant

        Property declarations in an object literal should not consider the prototype chain when being added to the new object
        https://bugs.webkit.org/show_bug.cgi?id=41929

        To fix this all we need to do is ensure that all new properties are
        added with putDirect rather than a fully generic call to put.  This
        is safe as an object literal is by definition going to produce a
        completely normal object.

        Rather than duplicating all the put_by_id logic we add an additional
        flag to op_put_by_id to indicate it should be using putDirect.  In
        the interpreter this adds a runtime branch, but in the jit this is
        essentially free as the branch is taken at compile time.  This does
        actually improve object literal creation time even in the interpreter
        as we no longer need to walk the prototype chain to verify that the
        cached put is safe.

        We still emit normal put_by_id code when emitting __proto__ as we want
        to get the correct handling for changing the prototype.

        Sunspider claims this is a 0.7% speedup which is conceivably real due
        to the performance improvement in object literals, but I suspect its
        really just the result of code motion.

        Make it possible to have both the JIT and Interpreter available in a single build
        https://bugs.webkit.org/show_bug.cgi?id=41722

        Separate the concept of !ENABLE(JIT) and ENABLE(INTERPRETER) and make it possible
        to have both JIT and INTERPRETER enabled at the same time.  This doesn't add
        support for mix mode execution, but it does allow a single build to contain all
        the code needed to use either the interpreter or the jit.

        If both ENABLE(INTERPRETER) and ENABLE(JIT) are true then setting the environment
        variable JSC_FORCE_INTERPRETER will force JSC to use the interpreter.

        This patch basically consists of replacing !ENABLE(JIT) with ENABLE(INTERPRETER),
        or converting #if ENABLE(JIT) ... #else ... into #if ENABLE(JIT) ... #endif
        #if ENABLE(INTERPRETER), etc.  There are also a few functions that need to be
        renamed to resolve return type ambiguity.

        Add clamping logic to function.apply similar to that
        enforced by firefox.  We have a smaller clamp than
        firefox as our calling convention means that stack
        usage is proportional to argument count -- the firefox

        Move BOM handling out of the lexer and parser
        https://bugs.webkit.org/show_bug.cgi?id=41539

        Doing the BOM stripping in the lexer meant that we could
        end up having to strip the BOMs from a source multiple times.
        To deal with this we now require all strings provided by
        a SourceProvider to already have had the BOMs stripped.
        This also simplifies some of the lexer logic.

        Bug 41238 - RegExp performance slow on Dromaeo benchmark

        Other javascript engines appear to cache prior results of regular

        Suggest adding some sort of caching mechanism to regular expression 
        processing.

        Added a single entry cache of match() results to RegExp class.

        Also added performance improvements to UString == operator.
        First check the impls for equality.  Then get the length of
        each of the non-null impls.  Next check the sizes for equality.
        Then check the data for the case of different impls that point 
        to the same data (most likely due to substrings from the beginning of
        another string).  Lastly we check the underlying data for equality.

        Custom-written JavaScript parser
        https://bugs.webkit.org/show_bug.cgi?id=34019

        Implement a recursive descent parser similar to that used by V8 and
        SpiderMonkey.  Greater than 2x improvement in SunSpider parsing tests.

        The parser consists of a JSParser class that uses a TreeBuilder to actually
        build the AST.  There are currently two builders -- the ASTBuilder and
        SyntaxChecker which separate the job of building an AST for code generation
        and simply checking syntactic correctness.

        There's still some less than ideal code remaining in the parser to allow
        us to retain the existing lexing code with minimal changes.  We'll tidy
        this up at a later date.

        Need to ensure that we grow the RegisterFile when creating a callframe for host code
        https://bugs.webkit.org/show_bug.cgi?id=40858
        <rdar://problem/8108986>

        In the past the use of the callframe in hostcode was much more
        limited.  Now that we expect the callframe to always be valid
        we need to grow the RegisterFile so that this is actually the
        case.  In this particular case the problem was failing to grow
        the registerfile could lead to a callframe that extended beyond
        RegisterFiler::end(), so vm re-entry would clobber the callframe
        other scenarios could also lead to badness.

        I was unable to construct a simple testcase to trigger badness,
        and any such testcase would be so dependent on exact vm stack
        layout that it would be unlikely to work as a testcase following
        any callframe or register allocation changes anyway.

        Thankfully the new assertion I added should help to catch these
        failures in future, and triggers on a couple of tests currently.

        The Qt::TextBypassShaping flag is used to tell Qt to
        only use the glyph advances.

        Qt 4.7 is needed to get this flag thus the complex path is always
        used if QtWebKit is compiled against an earlier version.

        Contrary to the WebKit's implementation, the complex code path
        is taken if the text is RightToLeft, justified or is formatted
        with non-zero letter or word spacing.

        Bug 40214 - Clean up error construction / throwing in JSC.
        
        The one egregious insanity here is that creating an error requires
        a VM-entry-esqe-host call (the string argument is wrapped as a JS
        object & pushed on the RegisterFile, then unwrapped back to a
        UString).  Changing this also means you only require a global
        object, not an ExecState, to create an error.

        The methods to create error objects are also parameterized
        requiring a switch on the type, which can be made cleaner and
        faster by moving to a separate method per error type.  Code to add
        divot information to error had been duplicated, and is coalesced
        back into a single function.

        Convenience methods added to create & throw type & syntax error
        with a default error message, since this is a common case.

        Also, errors are currently thrown either using
        "throwError(exec, error)" or "exec->setException(error)" - unify
        on the former, since this is more commonly used.  Add
        "throwVMError(exec, error)" equivalents, as a convenience for
        cases where the result was being wrapped in "JSValue::encode(...)".

        Simplified the host calling convention.
        
        22.5% speedup on 32-bit host function calls. 9.5% speedup on 64-bit host
        function calls.
        
        No change on SunSpider.
        
        All JS calls (but not constructs, yet) now go through the normal JS
        calling convention via the RegisterFile. As a result, the host calling
        convention, which used to be this

            JSValue (JSC_HOST_CALL *NativeFunction)(ExecState*, JSObject*, JSValue thisValue, const ArgList&)
            
        is now this

            JSValue (JSC_HOST_CALL *NativeFunction)(ExecState*)
            
        Callee, 'this', and argument access all hapen relative to the ExecState*,
        which is a pointer into the RegisterFile.
        
        This patch comes in two parts.
        
        PART ONE: Functional code changes.
        
        * wtf/Platform.h: Disabled optimized calls on platforms I didn't test.
        We can re-enable once we verify that host calls on these platforms are
        correct.

        * debugger/DebuggerCallFrame.cpp:
        (JSC::DebuggerCallFrame::functionName):
        (JSC::DebuggerCallFrame::calculatedFunctionName): Updated for change to
        ExecState::callee().

        (JSC::DebuggerCallFrame::thisObject): Updated for removal of ExecState::thisValue().

        * interpreter/CallFrame.cpp:
        * interpreter/CallFrame.h:
        (JSC::ExecState::callee):
        (JSC::ExecState::scopeChain):
        (JSC::ExecState::init): Changed callee() to be JSObject* instead of
        JSFunction* -- now, it might be some other callable host object.

        (JSC::ExecState::hostThisRegister):
        (JSC::ExecState::hostThisValue):
        (JSC::ExecState::argumentCount):
        (JSC::ExecState::argumentCountIncludingThis):
        (JSC::ExecState::argument):
        (JSC::ExecState::setArgumentCountIncludingThis):
        (JSC::ExecState::setCallee): Added convenient accessors for arguments
        from within a host function. Removed thisValue() because it was too
        tempting to use incorrectly, and it only had one or two clients, anyway.

        * interpreter/Interpreter.cpp:
        (JSC::Interpreter::callEval): Updated for removal of ExecState::thisValue().

        (JSC::Interpreter::throwException): Be sure to shrink the register file
        before invoking the exception handler, to reduce the chances that the
        handler will re-throw in the case of stack overflow. (Re-throwing is now
        more likely than it used to be, since standardizing the calling convention
        implicitly added stack overflow checks to some places where they used to be missing.)

        (JSC::Interpreter::execute): Clarified the scope of DynamicGlobalObjectScope.
        Updated for CallFrame::init API change.

        (JSC::Interpreter::executeCall): Clarified scope of DynamicGlobalObjectScope.
        Updated for CallFrame::init API change. Added support for calling a host
        function.

        (JSC::Interpreter::executeConstruct): Clarified scope of DynamicGlobalObjectScope.
        Updated for CallFrame::init API change. 

        (JSC::Interpreter::prepareForRepeatCall): Updated for CallFrame::init API change. 

        (JSC::Interpreter::privateExecute): Updated for CallFrame::init API change.
        Added some explicit JSValue(JSObject*) initialization, since relaxing
        the JSFunction* restriction on callee has made register types more ambiguous.
        Removed toThisObject() conversion, since all callees do it themselves now.
        Updated host function call for new host function signature. Updated for
        change to ExecState::argumentCount() API.

        * interpreter/Register.h:
        (JSC::Register::):
        (JSC::Register::operator=):
        (JSC::Register::function): Changed callee() to be JSObject* instead of
        JSFunction* -- now, it might be some other callable host object.

        * jit/JITOpcodes.cpp:
        (JSC::JIT::privateCompileCTINativeCall):
        * jit/JITOpcodes32_64.cpp:
        (JSC::JIT::privateCompileCTINativeCall): Deleted a bunch of code that
        set up the arguments to host functions -- all but one of the arguments
        are gone now. This is the actual optimization.

        * jit/JITStubs.cpp:
        (JSC::DEFINE_STUB_FUNCTION): Updated for ExecState and Register API
        changes noted above. Removed toThisObject() conversion, since all callees
        do it themselves now.
        
        * runtime/ArgList.h:
        (JSC::ArgList::ArgList): ArgList is getting close to unused. Added a
        temporary shim for converting from ExecState* to ArgList where it's still
        necessary.

        * runtime/Arguments.h:
        (JSC::Arguments::getArgumentsData):
        (JSC::Arguments::Arguments): Updated for ExecState and Register API
        changes noted above. 

        * runtime/CallData.cpp:
        (JSC::call): Changed call always to call Interpreter::executeCall, even
        for host functions. This ensures that the normal calling convention is
        set up in the RegsiterFile when calling from C++ to host function.

        * runtime/CallData.h: Changed host function signature as described above.

        * runtime/ConstructData.cpp:
        (JSC::construct): Moved JSFunction::construct code here so I could nix
        JSFunction::call and JSFunction::call. We want a JSFunction-agnostic
        way to call and construct, so that everything works naturally for non-
        JSFunction objects. 

        * runtime/JSFunction.cpp:
        (JSC::callHostFunctionAsConstructor):
        * runtime/JSFunction.h: Updated for ExecState and Register API changes
        noted above. Nixed JSFunction::call and JSFunction::construct, noted above.
 
        * runtime/JSGlobalObject.cpp:
        (JSC::JSGlobalObject::init): Ditto.

        PART TWO: Global search and replace.
        
        In the areas below, I used global search-and-replace to change
            (ExecState*, JSObject*, JSValue, const ArgList&) => (ExecState*)
            args.size() => exec->argumentCount()
            args.at(i) => exec->argument(i)

        Bug 39795 - Add support for YARR JIT generation of greedy quantified parens at the end of the main disjunction.
        (relanding r60267)

        If the last item in a main disjunction is a quantified set of parentheses,
        this is easier to code generate for than the general case for quantified
        parentheses. This is because we never need to backtrack into the parentheses
        - the first match will be the final and accepted match.

        This patch also somewhat reverts a recent change to when fallback to PCRE
        occurs. At the minute the compiler is tracking on patterns which will
        require JIT fallback. This is handy from a performance perspective (it saves
        the failed attempt at JIT compilation), but it means introducing knowledge
        of the JITs capabilities into the other layers of the regex compilers. For
        the specific feature of back-references, add a flag tracking their presence
        on the pattern, and make these expressions fallback without attempting to
        JIT. For parentheses, return to detecting which cases are have or have not
        been handled during JIT compilation.

        Bug 39643 - Clean up code generation in the JIT of stub function calls for op_call.

        Presently, as soon as op-call strays off the hot path we set up a set of values on
        the stack to be passed as arguments to cti functions, in case any should be called.

        Instead, hoist the setup of the callframe to happen slightly sooner, and make the
        cti functions to compile & check arity read these values from the callframe. This
        allows up to remove the deprecated methods to manually set up cti arguments, rather
        than using JITStubCall.h.
