[PATCH] D139601: [LoopVectorize] Clear cache of `LoopAccessInfoManager`

[Florian Hahn via Phabricator via llvm-commits]

fhahn added a comment.

> As #59319 describes, enabling LoopDistribute along with LoopVectorize causes an assertion to be hit. The reason seems to be because the LoopDistribute pass doesn't clear out the cache of the LoopAccessInfoManager.

This needs updating, the reason is that we cache LAI during LoopDistribute, LoopVectorize makes changes that invalidate SCEV and then we re-use the cache LAI which references invalid SCEV expressions.
