[PATCH] D45320: [MemDep] Fixed handling of invariant.group

dberlin added a comment.

During MemorySSA development, i'm pretty positive we tried some similar types of reverse maps, and while it did relatively okay on "llvm + clang testsuite", it fell down pretty hard in the real world from memory usage.

Adding George to see if he remembers any cases, so you have some stuff to test this all with.
He's on vacation, but i believe gets back next week.
