Add automatic prefix handling to yasm functions.  Does nothing now, but will be useful for porting x264 asm in the future.

The case for 16x16 blocks becomes 10 cpu cycles faster on pentium dual,
i could not find a speed difference in the case of subblocks though.

No speed change meassureable with START/STOP_TIMER, but this is needed
for future optimizations.

cathedral +0.5% speed
aladin +0.6% speed [note aladin has been cat-ed 10 times to reduce the influence
of init time]
Speedup also verified via START/STOP_TIMER (difference was very significant
for the changed parts)
