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).
