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.
