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

[Max Kazantsev via Phabricator via llvm-commits]

Addressed comments:

- Canonicalization split off;
- Checks are factored out into a separate function;
- Also separate checker for metadata, it also checks frequencies. I was unable to force BFI be non-null there, so the solution is somewhat clumsy.
