Expand description

Same as i8x16_shuffle, except operates as if the inputs were four 32-bit integers, only taking 4 indices to shuffle.

Indices in the range [0, 3] select from a while [4, 7] select from b. Note that this will generate the i8x16.shuffle instruction, since there is no native i32x4.shuffle instruction (there is no need for one since i8x16.shuffle suffices).
