[David Sherwood via Phabricator via llvm-commits]

- Addressed review comments, split off some of the refactoring into a NFC patch (D149659 <https://reviews.llvm.org/D149659>).
- Restricted tail-folding only to loops that exceed a certain instruction threshold, so that we get the benefit of interleaving for tight loops.
