[PATCH] D153453: [MemCpyOpt] implement single BB stack-move optimization which unify the static unescaped allocas

[Evgeny Eltsin via Phabricator via llvm-commits]

Heads up - we are seeing test failures that root cause to this revision.

More interesting, we are seeing some of these tests failing also under AddressSanitizer, complaining about stack-use-after-scope (https://github.com/google/sanitizers/wiki/AddressSanitizerUseAfterScope) - which seems to correspond well to the topic of this change.

We'll try to come up with a reproducer, but this might take time.
