Agreed! I hope to get to that next with the special casing and that way extracing i32x4 and storing wouldn't use movss but would instead use pextrd.

For AVX support this PR sort of conflicts with https://github.com/bytecodealliance/wasmtime/pull/5931, so I'll update this once that goes in and the helper will automatically use vmovs{s,d} for AVX.
