Sanjay Patel 752da31e95 [InstCombine] fold fneg into constant operand of fmul/fdiv ...

This accounts for the missing IR fold noted in D50195. We don't need any fast-math to enable the negation transform. 
FP negation can always be folded into an fmul/fdiv constant to eliminate the fneg.

I've limited this to one-use to ensure that we are eliminating an instruction rather than replacing fneg by a 
potentially expensive fdiv or fmul.
