[PATCH] D28934: Write a new SSAUpdater

[Daniel Berlin via Phabricator via llvm-commits]

dberlin added a comment.

Note that regardless of whether we want this for regular SSA or not, this will serve as the basis for my generic MemorySSA updater.
Sadly, because MemorySSA is not really part of the IR, and because it deals with may-defs, and not must-defs, we won't be able to share much beyond the idea.
(On the plus side, MemorySSA's semantics actually make generic updating easier and faster)
