Philipp Hancke c1f2a326d8 AVX2 column kernel for ScaleUVBox at 3x 
The box path costs +34% over point sampling, all of it the scalar column
pass. A UV pair is 32 bits, so vpaddw keeps U and V in separate
  halves and vpblendd + vpermd compacts every third pair. 96 bytes in, 16 out.

The +34% perf regression from the previous CL becomes +3%. Box width 3
only, AVX2 only; other widths need their own permute constants.
