[PATCH] D17157: Add the beginnings of an update API for preserving MemorySSA

[Daniel Berlin via llvm-commits]

dberlin added a comment.

This tests structural parts right now (IE that memoryssa is consistent and correct).  I will add the checks that the walker gives correct answers, but wanted to get a quick review before i proceeded much further down this path.
