Was not paying attention to which registers were for scratch. Avoid the need to preserve registers by not using registers in the Q4-Q7 range. Fix ScaleDown2Int_NEON by changing how rounding was applied. ScaleDownRow4 changed to process 4 output pixels per loop. No need to push/pop registers for UV Transpose, removed functions. Fix for CPU Flag for scale_test.cc to turn on/off optimizations for timing.
