[InlineCost] Add support for unary fneg. 

This adds support for unary fneg based on the implementation of BinaryOperator without the soft float FP cost.

Previously we would just delegate to visitUnaryInstruction. I think the only real change is that we will pass the FastMath flags to SimplifyFNeg now.
