[PATCH] D142109: [LoopVectorize] Remove runtime check and scalar tail loop when tail-folding.

[Sander de Smalen via Phabricator via llvm-commits]

sdesmalen updated this revision to Diff 493286.
sdesmalen added a comment.

Rebased the patch on top of D142887 <https://reviews.llvm.org/D142887>, and added a new enum 'DataAndControlFlowWithoutRuntimeCheck' to distinguish it from 'DataAndControlFlow'.
