FMF on fcmps

[tschuett]

I looked at this line:

llvm-project/llvm/lib/Transforms/InstCombine/InstCombineVectorOps.cpp

Line 490 in d9c4c31

return CmpInst::Create(cast<CmpInst>(SrcVec)->getOpcode(), Pred, E0, E1);

It does not pass the flags from the matched compare to the newly created. According to the langref fcmps have FMF.

There is no CmpInst::CreateWithCopiedFlags constructor.

I would like to work on this
