[PATCH] D70286: Merge memtag instructions with adjacent stack slots.

[Evgenii Stepanov via Phabricator via llvm-commits]

eugenis updated this revision to Diff 235973.
eugenis added a comment.

Cleaned up the code and extended it to allow gaps in a sequence of memory tagging instructions (in which case subsequences before and after the gap would be optimized separatly).
