Ng Zhi An c03354b430 Reland "[wasm-simd][arm64] Fuse add and extmul" 
This is a reland of 65515ddd3e

Fix is to use AddWithWraparound for signed additions to avoid UB.

Original change's description:
> [wasm-simd][arm64] Fuse add and extmul
>
> We can select a better instruction for add+extmul, using one of the
> multiply-long-accumulate instruction.
>
> Define a helper struct to pattern match Add(x, OP(y, z)) and
> Add(OP(x, y) z), and ensure that the matched OP is always on the
> LHS, to simplify checking for matches.
