[PATCH] D69617: [LoopUnroll] countToEliminateCompares(): fix handling of [in]equality predicates (PR43840)

[Roman Lebedev via Phabricator via llvm-commits]

lebedev.ri updated this revision to Diff 227953.
lebedev.ri added a comment.

Fix edge-case handling - if we need to peel that one extra iteration,
we should still respect the `MaxPeelCount`, and if we aren't allowed
to peel, we should give up, not do subpar peeling job.
