[PATCH] D123865: [LoopPeel] Allow partial unrolling for profile-based peeling

[Igor Kudrin via Phabricator via llvm-commits]

A bit of the context. After D71990 <https://reviews.llvm.org/D71990>, we noticed that one of our tests became slower and did not benefit from PGO. The test has a loop that is executed exactly 8 times, and, before the patch, it was (partially) unrolled but after the patch, the loop is preserved in the compact form.
