[PATCH] D73978: [WIP][FPEnv] Don't transform FSUB(-0.0,X)->FNEG(X) when flushing denormals

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added a comment.

The DenormalMode::Invalid is a temporary state and should not really be a concern. It should be invalid and never seen after D69989 <https://reviews.llvm.org/D69989>
