This reverts commit d2ce5744.

Reason for revert: We reverted the early canonicalization change, so we need to worry about non-canonicalized shuffles now.

Original change's description:
> [wasm-simd][arm64] Update f32x4.mul(dup) pattern matching
>
> We now canonicalize earlier in the pipeline, and don't need to worry
> about non-canonicalized shuffles.
