[llvm] r278573 - [LoopVectorize] Detect loops in the innermost loop before creating InnerLoopVectorizer

[Hans Wennborg via llvm-commits]

Oh, also needed to merge r278678 for the Clang-side of those refactorings.

Please let me know if there were any other dependencies or issues with
those that I should know about.

Cheers,
Hans
