[PATCH] D27846: [SLP] Support for horizontal min/max reduction

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added a comment.

I think its almost there now, my only concern is that we're not discriminating between signed/unsigned in getMinMaxReductionCost calls - e.g. SSE is very inconsistent with support for these.
