* vgbbd VRT,VRB - Vector Gather Bits by Bytes by Doubleword
*
* All ith bits (i in range 1 to 8) of each byte of doubleword element in source
* register are concatenated and placed into ith byte of appropriate doubleword
* element in destination register.
*
* Following solution is done for both doubleword elements of source register
* in parallel, in order to reduce the number of instructions needed(that's why
* arrays are used):
* First, both doubleword elements of source register vB are placed in
* appropriate element of array avr. Bits are gathered in 2x8 iterations(2 for
* loops). In first iteration bit 1 of byte 1, bit 2 of byte 2,... bit 8 of
* byte 8 are in their final spots so avr[i], i={0,1} can be and-ed with
* tcg_mask. For every following iteration, both avr[i] and tcg_mask variables
* have to be shifted right for 7 and 8 places, respectively, in order to get
* bit 1 of byte 2, bit 2 of byte 3.. bit 7 of byte 8 in their final spots so
* shifted avr values(saved in tmp) can be and-ed with new value of tcg_mask...
* After first 8 iteration(first loop), all the first bits are in their final
* places, all second bits but second bit from eight byte are in their places...
* only 1 eight bit from eight byte is in it's place). In second loop we do all
* operations symmetrically, in order to get other half of bits in their final
* spots. Results for first and second doubleword elements are saved in
* result[0] and result[1] respectively. In the end those results are saved in
* appropriate doubleword element of destination register vD.
