[PATCH] D146978: [Assignment Tracking][NFC] Improve removeRedundantDbgLocsUsingBackwardScan

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

Orlando added a comment.

I think some kind of custom interval map could possibly yield further improvements, but combining the two patches (second one coming shortly) already gives a geomean 0.3% reduction in instructions retired in a CTMark LTO-O3-g build.
