Port x264 deblocking code to libavcodec.  This includes SSE2 luma deblocking code and both MMXEXT and SSE2 luma intra deblocking code for H.264 decoding.  This assembly is available under --enable-gpl and speeds decoding of Cathedral by 7%.

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.
