[PATCH] D98627: [JumpThreading] Do not use AA after a block has been destroyed. PR43276

[Max Kazantsev via Phabricator via llvm-commits]

mkazantsev added a comment.

The real problem is that functions like `MergeBasicBlockIntoOnlyPred` may be applied to a loop block, and in fact make the affected block not part of the loop. No one updates the loop info inside the AA accordingly. Maybe we can fix it...
