Currently, the machine combiner can proceed matching when -ffast-math is on. It should also match when only -ffp-contract=fast is specified as was the case before when DAGCombiner was doing the job. Patch by: Abderrazek Zaafrani <a.zaafrani@samsung.com>. Differential Revision: https://reviews.llvm.org/D24366 llvm-svn: 281649
