[PATCH] D136320: [Assignment Tracking Analysis][1/*] Add analysis pass core

[Orlando Cazalet-Hyams via Phabricator via llvm-commits]

Orlando updated this revision to Diff 480875.
Orlando added a comment.

Fix another bug to do with fragments that was found with a new test in D136335 <https://reviews.llvm.org/D136335>. In short: we weren't checking for matching assignments to fragments contained within a fragment, so a def of a larger fragment would still be considered live after a def to a contained fragment (if the larger fragment assignment was queried only).
