[PATCH] D125712: [SLP][X86] Improve reordering to consider alternate instruction bundles

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added a comment.

Lets get the shuffle mask arg added - we need that to correctly cost alt patterns. We might be able to reduce the SLP impact to a getAltCost() wrapper of some kind.
