05416e2d9a Box filter for YUV use rows with accumulation buffer for better memory behavior. The old code would do columns accumulated into registers, and then store the result once. This was slow from a memory point of view. The new code does a row of source at a time, updating an accumulation buffer every row. The accumulation buffer is small, and should fit cache. Before each accumulation of N rows, the buffer needs to be reset to zero. If the memset is a bottleneck, it would be faster to do the first row without an add, storing to the accumulation buffer, and then add for the remaining rows.

cfce47efc8 Change Sobel to use JPeg Luma calculation instead of extracting G channel. Using luma produces a better sobel that respects all 3 channels of RGB. Historically the G channel was used to improve performance, and because the luma of I420 is a constrained range, hurting quality. Using the JPeg variation of YUV, the luma is more accurate, including cross platform, better optimized for AVX2 and odd widths, and full range.

d28cd77f99 Enable assembly for clangcl build on Windows. Previously assembly was disabled so clangcl would work, but only with C code. As clangcl mimics both Visual C and GCC, ifdefs need to pick one or the other or often you'll end up with both. In this CL we disable most Visual C code and use the GCC versions which allow assembly for both 32 and 64 bit intel.

92f7f421fd rename I400 to J400 and I400 reference to I400. J400 is a simple replication of values to convert to RGB, which is what the old I400 was. I400 reference is the Y part of the YUV formula, so renaming that to I400.
