[PATCH] D99249: [PassManager] Run additional LICM before LoopRotate

[Artem Belevich via Phabricator via llvm-commits]

tra added a comment.

FYI, this appears to introduce a somewhat serious performance regression for NVPTX.

It's not necessarily a bug, but rather an unfortunate interaction between loop transforms blocking SROA which affects performance-sensitive quirk in NVPTX, where local storage is actually quite expensive.
