[PATCH] D87972: [OldPM] Pass manager: run SROA after (simple) loop unrolling

[Fangrui Song via Phabricator via llvm-commits]

MaskRay added a comment.

I have tested this patch internally and seen gains and losses. On one document search related benchmark 3~5% improvement. One zippy (snappy) there is 3~5% regression. Perhaps we do need a conditional extra SROA run.
