Keno Fischer 7db4634bdb [AliasSetTracker] Don't drop AA MD so eagerly ... Summary: When we have patterns like loop: %la = load %ptr, !tbaa %lba = load %ptr, !tbaa !noalias AliasSetTracker would previously think that the two types of annotation for the pointer conflict, dropping both for the purpose of determining alias sets. That is clearly way too conservative, as the tbaa is still valid whether or not one of the memory accesses has additional AA metadata. We could go one step further and attempt to properly merge the AA metadata, but it's not clear that that would be worth it since that may introduce additional MD nodes, which may be undesirable since this is merely an Analysis.
