[PATCH] D58616: [Vectorizer] Add vectorization support for fixed smul/umul intrinsics

[Simon Pilgrim via Phabricator via llvm-commits]

Herald added a project: LLVM.

This requires a couple of tweaks to existing vectorization functions as they were assuming that only the second call argument (ctlz/cttz/powi) could ever be the 'always scalar' argument, but for smul.fix + umul.fix its the third argument.
