[PATCH] D46706: [PM/LoopUnswitch] Support partial trivial unswitching.

[Fedor Sergeev via Phabricator via llvm-commits]

fedor.sergeev added a comment.

Not exactly related to this set of changes...
I just have discovered that old LoopUnswitch performs SCEV cache invalidation when it does nontrivial updates to CFG
 (forgetLoop in LoopUnswitch::unswitchNontrivialCondition) .

Perhaps makes sense to do the same in new loop unswitch as well?
