[x64][ia32] Add Support for the Float64Neg and Float32Neg turbofan operators.

[x64][ia32] Add Support for the Float64Neg and Float32Neg turbofan operators.

Benedikt, do you think we could also provide these operators on mips,
maybe by expanding them to "-0.0 -x"? If mips can provide these operators,
then we could make Float64Neg and Float32Neg real operators and not just
OptionalOperators.
