- negation of COMPLEX_CST if both real and imaginary parts can be

- here. Always negate integer constants unless we honor -ftrapv
- and the signed type would overflow. Always negate real constants
- unless we honor -ftrapping-math. Only convert -(A-B) into B-A
- if allowed by reorder_operands_p. Add support for COMPLEX_CST.
