[PATCH] D106353: [PowerPC] use lfiwax/lfiwzx for scalar_to_vector + load at PWR7

[ChenZheng via Phabricator via llvm-commits]

shchenz added a comment.

Even for the above case, I think we should fix it when we legalize the type `v4i8`. Since we already added many types of LD_SPLAT nodes, we should generate an `LD_SPLAT` node instead of `scalar_to_vector(load)` for the type legalizing now.

FYI @nemanjai If you think this is still needed, please let me know. Thanks.
