[PATCH] D50392: [TargetLowering] Add support for non-uniform vectors to BuildExactSDIV

[Simon Pilgrim via Phabricator via llvm-commits]

Rebased.

I've refactored the approach slightly to demonstrate ISD::matchUnaryPredicate being used to iterate over a scalar or the elements of a vector. - this could be used in TargetLowering::BuildUDIV as well to make the equivalent code easier to understand.
