  [MemDep] Use BatchAA in more places (NFCI)

Previously, we already used BatchAA for individual simple pointer
dependency queries. This extends BatchAA usage for the non-local
case, so that only one BatchAA instance is used for all blocks,
instead of one instance per block.

Use of BatchAA is safe as IR cannot be modified during a MemDep
query.
