[PATCH] D50650: [MemorySSA] Add API to update an incoming block into a MemoryPhi.

This can actually be done with the more generic wireOldPredecessorsToNewImmediatePredecessor. 
There's some extra work in the generic one with creating a new phi and then deleting it, but it may be better than having another API.
George, let me know if you agree with using the generic one and I'll abandon this revision. Thanks!
