[DSE,MemorySSA] Use BatchAA for AA queries.
We can use BatchAA to avoid some repeated AA queries. We only remove
stores, so I think we will get away with using a single BatchAA instance
for the complete run.
The changes in AliasAnalysis.h mirror the changes in D85583.
The change improves compile-time by roughly 1%.
