[PATCH] D43269: [MemorySSA] Be less aggressive with @llvm.lifetime.start

[Nuno Lopes via Phabricator via llvm-commits]

nlopes added a comment.

Given that the original motivation for these lifetime intrinsincs was for inlining, I don't see a reason to support multiple start/ends on the same pointer.
Or is there another new use case that I'm unaware of?  Also, we don't have any transformation splitting (or even shrinking I think) these lifetimes.
