cc88adc620 YUV scale filter columns improved filtering accuracy 
upscale a YUV image.  observe change in hue.. green especially.
disable ScaleFilterCols_SSSE3, falling back on ScaleFilterCols_C
observe hue.. green especially, is better.

was ScaleFrom1280x720_Bilinear (1620 ms)
now ScaleFrom1280x720_Bilinear (1907 ms)

cf101116c9 Remove initialize to zero on output variables for inline. 
Inline that uses temporary variables is currently initializing them
to 0 and passing in as output "+r".
This CL replaces the output constraint to "=&r" for most meaning an
output with early write (before inputs).  This allows the initialize
to zero step to be removed, saving 1 instruction.
