684 * First, both doubleword elements of source register vB are placed in

686 * loops). In first iteration bit 1 of byte 1, bit 2 of byte 2,... bit 8 of
687 * byte 8 are in their final spots so avr[i], i={0,1} can be and-ed with
688 * tcg_mask. For every following iteration, both avr[i] and tcg_mask variables
689 * have to be shifted right for 7 and 8 places, respectively, in order to get
690 * bit 1 of byte 2, bit 2 of byte 3.. bit 7 of byte 8 in their final spots so
691 * shifted avr values(saved in tmp) can be and-ed with new value of tcg_mask...
692 * After first 8 iteration(first loop), all the first bits are in their final
693 * places, all second bits but second bit from eight byte are in their places...
694 * only 1 eight bit from eight byte is in it's place). In second loop we do all
695 * operations symmetrically, in order to get other half of bits in their final
696 * spots. Results for first and second doubleword elements are saved in
697 * result[0] and result[1] respectively. In the end those results are saved in
