BasicAA stores a reference to LoopInfo inside. This imposes an implicit requirement of keeping it up to date whenever we modify the IR (in particular, whenever we modify terminators of blocks that belong to loops). Failing to do so leads to incorrect state of the LoopInfo. Because general AA does not require loop info updates and provides to API to update it properly, the users of AA reasonably assume that there is no need to update the loop info. It may be a reason of bugs, as example in PR43276 shows. This patch drops dependence of BasicAA on LoopInfo to avoid this problem. This may potentially pessimize the result of queries to BasicAA.
