[PATCH] D134663: [LoopDeletion] Clear block & loop dispo cache after breaking backedge.

[David Blaikie via Phabricator via llvm-commits]

dblaikie added a comment.

While I guess this is a fix for crash/UB, was the problem covered by any tests or could we add test coverage? (or maybe the failure's so unlikely as to be impractical to test - some ABA allocation situation which rarely occurs?)
