We missed certain updates, mostly to call site information, and dependent AAs did not get recomputed. We also did not properly distinguish and propagate incoming and outgoing information of call sites. The runtime tests passes now, I'll add a proper test for AAExecutionDomain soon that covers all the cases and ensures we haven't forgotten more updates. To help unblock some apps, I'll put the fix first.
