Allow assemblers with a slightly different syntax to use
the optimized neon routines.

Removed extra constraints on the calling of the optimized
routines.  All neon routines can load unaligned and handle
odd widths.

Align allocated buffers in rotate_test.cc

Add neon rotate file to gyp file for arm targets.

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.
