* Motion Compensation frequently needs to average values using the
* formula (x+y+1)>>1. Both MMXEXT and 3Dnow include one instruction
* to compute this, but it's been left out of classic MMX.
*
* We need to be careful of overflows when doing this computation.
* Rather than unpacking data to 16-bits, which reduces parallelism,
* we use the following formulas:
*
* (x+y)>>1 == (x&y)+((x^y)>>1)
* (x+y+1)>>1 == (x|y)-((x^y)>>1)
