Craig Topper 50d502826b [CostModel] Add really basic support for being able to query the cost of the FNeg instruction. 
Summary:
This reuses the getArithmeticInstrCost, but passes dummy values of the second
operand flags.

The X86 costs are wrong and can be improved in a follow up. I just wanted to
stop it from reporting an unknown cost first.
