Philip Reames ca587fe0b4 [EarlyCSE] Reuse invariant scopes for invariant load 
This is a follow up to https://reviews.llvm.org/D43716 which rewrites the invariant load handling using the new infrastructure. It's slightly more powerful, but only in somewhat minor ways for the moment. It's not clear that DSE of stores to invariant locations is actually interesting since why would your IR have such a construct to start with?

Note: The submitted version is slightly different than the reviewed one.  I realized the scope could start for an invariant load which was proven redundant and removed.  Added a test case to illustrate that as well.

Differential Revision: https://reviews.llvm.org/D44497
