[PATCH] D143283: [AArch64][SVE]: custom lower AVGFloor/AVGCeil. [WIP]

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

Please pre-commit the new testcases, so the changes are more visible.

The `<vscale x 2 x i128>` variations currently crash the compiler; I'd recommend fixing that before trying to optimize them.

The "expected" code for haddu_v2i32 is worse than what we currently generate.
