[PATCH] D77137: [Reassociate] Preserve AAManager and BasicAA analyses

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

In general, it's possible for a pass to preserve GlobalsAA, and not BasicAA.  BasicAA depends on a number of different analysis passes, like LoopInfo, which might not be updated.  GlobalsAA doesn't depend on any local analysis passes, so it's much simpler to preserve.
