We're currently losing any fast-math flags when synthesizing fcmps for min/max reductions. In LV, make sure we copy over the scalar inst's flags. In LoopUtils, we know we only ever match patterns with hasUnsafeAlgebra, so apply that to any synthesized ops. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@248201 91177308-0d34-0410-b5e6-96231b3b80d8
