[PATCH] D83537: [WebAssembly] Use ISD::SPLAT_VECTOR for splats

[Thomas Lively via Phabricator via llvm-commits]

tlively planned changes to this revision.
tlively added a comment.

This whole patch got a whole lot more complex than I thought it would be at first, so I'm going to split out some of the separately-useful parts and experiment with other ways of getting rid of the undef lanes in splat build_vectors.
