  x86: Minor mbtree_propagate_cost improvements
  
  Reduce the number of registers used from 7 to 6.
  Reduce the number of vector registers used by the AVX2 implementation from 8 to 7.
  Multiply fps_factor by 1/256 once per frame instead of once per macroblock row.
  Use mova instead of movu for dst since it's guaranteed to be aligned.
  Some cosmetics.
