[PATCH] D110922: [LoopPeel] Peel loops with deoptimizing exits

[Dmitry Makogon via Phabricator via llvm-commits]

dmakogon added a comment.

Fixed crash on `test/Transforms/LoopUnroll/revert-D110922.ll`. It happened due to adding the same edges to DomTree due to the fact that one of the loop exiting blocks had a `switch` terminator and there were multiple edges from that exiting block to an exit. Now we construct a set from the loop exiting edges and then add edge insertion updates only for edges from the set.
