Fiona Glaser 5a0d6b758c DAGCombiner: don't duplicate (fmul x, c) in visitFNEG if fneg is free ...

For targets with a free fneg, this fold is always a net loss if it
ends up duplicating the multiply, so definitely avoid it.

This might be true for some targets without a free fneg too, but
I'll leave that for future investigation.
