[PATCH] D49242: [Intrinsics] define funnel shift IR intrinsics + DAG builder support

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added a comment.

It might be better to split the tests down into separate files a little - illegal types, rotation patterns etc?  I have a feeling these test files might grow and become unwieldy. Possibly add i686 tests as well after that.
