358b5b1a59 Get rid of mb2b8_xy and b8_stride, change arrays organized based on b8_stride to 
ones based on mb_stride in h264.
about 20 cpu cycles faster overall per MB

19769ece3b H264: use alias-safe macros 
This eliminates all aliasing violation warnings in h264 code.
No measurable speed difference with gcc-4.4.3 on i7.

af0d6581e1 Restructure spatial direct MV generation so that the zero predictior shortcut 
is closer at the top.
50-130 cpu cycles faster depending on which kind of direct MBs are meassured.

edb4df436f Split spatial and temporal direct MV generation. 
A little  faster and needed for future optimizations.
This sadly leads to some code duplication (which i hope i can factor out
again after the optimizations on the direcr mv code are done)

828cfff63d Pack MVs together from the begin for spatial direct, this simplifies the code 
and is a bit faster (5-10 cpu cycles depending on what is meassured).
