[PATCH] D51646: DAG: Preserve FMF when creating fminnum/fmaxnum

[Matt Arsenault via Phabricator via llvm-commits]

arsenm created this revision.
arsenm added a reviewer: spatel.
Herald added a subscriber: wdng.

These should preserve the fast math flags on the initial fcmp.
Without this, the nodes may later be expanded to use an
unnecessary quieting operation.
