[PATCH] D136233: [SimpleLoopUnswitch] Inject loop-invariant conditions and unswitch them when it's profitable

[Max Kazantsev via Phabricator via llvm-commits]

mkazantsev updated this revision to Diff 493280.
mkazantsev added a comment.

Rolled back to last working version (effectively undone changes from last request).

- Removal of canonicalization cripples the transform to a point where it makes no sense. Function renamed into `canonicalizePredicate`.
- Profitability check cripples the transform to doing nothing. Trying to understand why.
