Original change's description:
> [wasm-simd] Fix extract lane unsigned extend
>
> The interpreter is missing a static cast when extracting lanes smaller
> than int32_t and doing an unsigned extend. The array in Simd128 is
> signed, so a direct cast to uint32_t will be a signed extension. The fix
> is to, in the unsigned case, cast to unsigned (of the appropriate size)
> first, then cast to uint32_t.
