1900 negation of COMPLEX_CST if both real and imaginary parts can be
1901 negated. Allow negation through floating point extensions and

1904 here. Always negate integer constants unless we honor -ftrapv
1905 and the signed type would overflow. Always negate real constants

1907 if allowed by reorder_operands_p. Add support for COMPLEX_CST.
