[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 495478.
mkazantsev added a comment.

Fixed 2 minor bugs:

- Degenerate profile {0, 0} is now rejected;
- Do not use `Builder.CreateICmp` for injected condition creation, as it may generate a constant and break further logic. Leave this simplification for the further passes.
