[PATCH] D29064: [MemorySSA] Add invariant.group handling

[Daniel Berlin via Phabricator via llvm-commits]

A few things

1. I'm curious why this isn't just added to the use optimizer more directly, it looks like you are computing info about most-dominating accesses, etc, which the stack already has.
2. If this isn't done in the walker, it'll never work in the face of updates.
