[PATCH] D129636: Fix a LSR debug invariance issue

[Markus Lavin via Phabricator via llvm-commits]

markus updated this revision to Diff 449653.
markus added a comment.

Not sure if this ended up so well as it appears that `getExistingSCEV` was a private method and I am uncertain if we can or should make it public. Either way if we decide to go this route then we probably should add explicit tests for this part as well (i.e. to make sure that the forgetting of SCEV does not produce another invariance issue).
