[PATCH] D62625: LFTR for multiple exit loops

[Philip Reames via Phabricator via llvm-commits]

reames updated this revision to Diff 204387.
reames added a comment.

rebase on requested tests

Just to note, I'm deliberately not adding any tests for possibly poison IVs.  I don't think there are any unique issues for multiple exit IVs, and giving that I want to leave the coverage concentrated on things which are unique to multiple exits.
