ARGBToAR30Row:
Red Blue
With the 8 bit value in the upper bits of a short, vpmulhuw by (1024+4) will
produce a 10 bit value in the low 10 bits of each 16 bit value. This is whats
wanted for the blue channel. The red needs to be shifted 4 left, so multiply by
(1024+4)*16 for red.
Alpha Green
Alpha and Green are already in the high bits so vpand can zero out the other
bits, keeping just 2 upper bits of alpha and 8 bit green. The same multiplier
could be used for Green - (1024+4) putting the 10 bit green in the lsb. Alpha
would be a simple multiplier to shift it into position. It wants a gap of 10
above the green. Green is 10 bits, so there are 6 bits in the low short. 4
more are needed, so a multiplier of 4 gets the 2 bits into the upper 16 bits,
and then a shift of 4 is a multiply of 16, so (4*16) = 64. Then shift the
result left 10 to position the A and G channels.
