[PATCH] D121354: [SLP] Fix lookahead operand reordering for splat loads.

[Vasileios Porpodas via Phabricator via llvm-commits]

vporpo added a comment.

Wdyt about something like `ShuffleKind::SK_BroadcastForBroadcastLoad` that only takes into consideration the shuffle part of a broadcast load? A normal broadcast of a double to a 2-wide vector costs 1, so this could cost 0.
