  mbaff: fix mb_field_decoding_flag tracking and simplify allow skip check
  
  Fixes an issue with too many forced non-skips in mbaff+cavlc, as well as
  non-deterministic output with mbaff+cavlc+sliceQ-threads.

  Macroblock tree overhaul/optimization
  
  Move the second core part of macroblock tree into an assembly function;
  SIMD-optimize roughly half of it (for x86). Roughly ~25-65% faster mbtree,
  depending on content.
  
  Slightly change how mbtree handles the tradeoff between range and precision
  for propagation.
  
  Overall a slight (but mostly negligible) effect on SSIM and ~2% faster.
