Expand description

Packs two N-bit integer vectors to a single N/2-bit integers.

The conversion from N-bit to N/2-bit should be provided by f.

Each 128-bit chunk is treated independently (i.e., the value for the is i-th 128-bit chunk of dest is calculated with the i-th 128-bit chunks of left and right).
