[PATCH] D48578: use a MapVector for pass manage LastUser

[Jay Foad via Phabricator via llvm-commits]

foad added a comment.

> If you want to fix this, you should fix the bad algorithm in setLastUser. We already have an inverse map, so there should be some way that simply doesn't iterate over the entire thing in this way.

I've done this in D92309 <https://reviews.llvm.org/D92309>.
