Probably [this c-t-t test](https://llvm-compile-time-tracker.com/compare.php?from=9c52b735ea04f58c04ac36c162ed8e45412287b3&to=5dc86c4710dee1dbd9e576e5846b37081e8aef3a&stat=instructions:u); minor barely significant improvement for a fair amount of complexity. Primary benefit is removing PopulateLoopDFS and reducing the size of deeply nested loops when unmodified.
