Original change's description:
> [wasm-simd] Fix scalar lowering of kParameter
> 
> Lowers the call descriptor of a wasm function if it contains simd.
> 
> Also fixes a couple of issues with the lowering of kParameter:
> - the old_index == new_index check is incorrect, it would only work if
> the s128 parameter is the first parameter
> - the old_index was also not adjusted to account for Parameter[0] being
> the wasm instance object
> - new_index needs to be adjusted to account for the instance object too
> 
> These fixes make it more similar to the lowering of kParameter in
> int64-lowering.c.
> 
> Also add a new mjsunit test to exercise this logic.
