Daniel Berlin 1627603e25 Add the beginnings of an update API for preserving MemorySSA ...

Summary:
This adds the beginning of an update API to preserve MemorySSA.  In particular,
this patch adds a way to remove memory SSA accesses when instructions are
deleted.

It also adds relevant unit testing infrastructure for MemorySSA's API.

(There is an actual user of this API, i will make that diff dependent on this one.  In practice, a ton of opt passes remove memory instructions, so it's hopefully an obviously useful API :P)
