  x86: Add asm for mbtree fixed point conversion
  
  The QP offsets of each macroblock are stored as floats internally and
  converted to big-endian Q8.8 fixed point numbers when written to the 2-pass
  stats file, and converted back to floats when read from the stats file.
  
  Add SSSE3 and AVX2 implementations for conversions in both directions.
  
  About 8x faster than C on Haswell.
