053074276b Drop compute_mb_neighbors() and move fill_decode_neighbors() up to take its 
role.
Should be faster as this is a strict code removial.

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)
