We should never give up on AAIsDead as it guards other AAs from unreachable code (in which SSA properties are meaningless). We did however use required dependences on some queries in AAIsDead which caused us to invalidate AAIsDead if the queried AA got invalidated. We now use optional dependences instead. The bug that exposed this is added to the liveness.ll test and other test changes show the impact. Bug report by @sdmitriev.
