Expand description

Same as `i8x16_shuffle`, except operates as if the inputs were two 64-bit integers, only taking 2 indices to shuffle.

Indices in the range [0, 1] select from `a` while [2, 3] select from `b`. Note that this will generate the `v8x16.shuffle` instruction, since there is no native `i64x2.shuffle` instruction (there is no need for one since `i8x16.shuffle` suffices).
