Original change's description:
> [wasm-simd][ia32][x64] Only use registers for shuffles
>
> Shuffles have pattern matching clauses which, depending on the
> instruction used, can require src0 or src1 to be register or not.
> However we do not have 16-byte alignment for SIMD operands yet, so it
> will segfault when we use an SSE SIMD instruction with unaligned
> operands.
>
> This patch fixes all the shuffle cases to always use a register for the
> input nodes, and it does so by ignoring the values of src0_needs_reg and
> src1_needs_reg. When we eventually have memory alignment, we can
> re-enable this check, without mucking around too much in the logic in
> each shuffle match clause.
