[PATCH] D158399: [WebAssembly] Optimize vector shift using a splat value from outside block

[Craig Topper via Phabricator via llvm-commits]

craig.topper added a comment.

Could this use the `TargetLowering::shouldSinkOperands` hook to get CodeGenPrepare to move the splat into the loop. ARM, X86, and RISC-V all do that.
