[PATCH] D96174: [SelectionDAG][AArch64] Restrict matchUnaryPredicate to only handle SPLAT_VECTOR for scalable vectors.

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added a comment.

matchUnaryPredicate was added to try to encourage people to add full (non-uniform) vector support without too much legwork - a lot of combines still just have scalar / uniform support only. I'm just worried that if they have to do extra work to handle different vector cases it'll further discourage vector handling.
