The proposal SGTM!
I was somewhat surprised this doesn't affect compile time at all, with it doing AA checks on all MemoryLocation pairs, but this seems to indeed not have any impact (tested on internal benchmarks too). My assumption is that most alias checks are taking advantage of the cache in BatchAA.

I'll follow up with inline comments.
+1 to update method names to match the change to tracking memory locations, and update comments.
