[PATCH] D115829: Allow calls with known writes when trying to remove allocas

[Philip Reames via Phabricator via llvm-commits]

reames added a comment.

Note for future self: We can sink most of the logic above into MemoryLocation::getForDest, and pickup DSE of the single alloca cases for free.  Would be a good cleanup to do, though needs some additional tests written.  Oddly, DSE appears not to remove trivial lifetime pairs.
