huihuiz added a comment to rL350514: Regenerate test..

Use pattern matching should be a better approach.

Clear the LoopToAliasSetMap only when the loop being deleted is outermost loop
or removed from its parent. Otherwise, the alias information saved by its subloops
is cached, and later collected and erased by their nearest outer loop.
