Expand description

Same as `i8x16_shuffle`, except operates as if the inputs were eight 16-bit integers, only taking 8 indices to shuffle.

Indices in the range [0, 7] select from `a` while [8, 15] select from `b`. Note that this will generate the `i8x16.shuffle` instruction, since there is no native `i16x8.shuffle` instruction (there is no need for one since `i8x16.shuffle` suffices).
