This change updates a few of the transformations in foldFMulReassoc to respect absent fast-math flags in cases where fmul and fdiv, fadd, or fsub instructions were being folded but the code was only checking for fast-math flags on the fmul instruction and was transferring flags to the folded instruction that were not present on the other original instructions.
