[PATCH] D92309: [LegacyPM] Update InversedLastUser on the fly. NFC.

[serge via Phabricator via llvm-commits]

serge-sans-paille added a comment.

As the state of `LastUser` are closely tied, it would make sense to encapsulate the two members in a class that would maintain the consistency of these two states, so that the two new operations `recordNewUser(Pass, User)` and `updatelastUser(Pass, User)` become explicit ?
