[PATCH] D139275: [SimplifyCFG] `FoldBranchToCommonDest()`: deal with mismatched IV's in PHI's in common successor block

[Arthur Eubanks via Phabricator via llvm-commits]

aeubanks added a comment.

just wanted to note that this did increase binary size in some places (https://bugs.chromium.org/p/chromium/issues/detail?id=1401820), even though the description claims it will basically never fire. (I'm not blocking anything on that, just a note)

separately, IMO this patch is non-trivial enough to deserve an lgtm before landing
