311add63c2 CopyRow_NEON use ldp instead of ld1 for better performance. 
Under cache thrashing circumstances, ldp/stp perform better than
ld1/st1 on QC820/QC821 CPUs.  Same performance when hitting cache.

efbf15754a Step thru full color test by increments of 5 for better test speed. 
Full color test is the slowest of the unittests, and not catching any
additional bugs at the moment.  Step thru range of 0 to 255 in steps of
5 to speed up the test.  255 is 3 * 5 * 17, so any of those primes would
hit 0 and 255 exactly.

f0a9d6d206 Gaussian reorder for benefit of A73 
Roughly. instead of 4 loads and 8 multiples, use 1 load and 2 multiples
4 times over.  The original code, as with the C code from clang and gcc,
did all the loads, then all the math, then the store.  The new code
does a load, then the math, then the next load, etc.
This schedules better on current arm 64 cpus.
Number of registers also reduced, reusing the same registers.

76a599ec3b fix jpeg and bt.709 yuvconstants for neon64. 
yuv constants for bt.601 were previously ported to neon64, as well
as the code to respect other color spaces.  But the jpeg and bt.709
colour conversion constants were still in armv7 form.  This changes
the constants for aarch64 builds to be compatible with the code.

yuv constants are now passed as const *

Remove Yvu constants which were used for older version on nv21 but not new code.

013080f2d2 Pass yuvconstants to YUV conversions for neon 64 bit 
SETUP provided by zhongwei.yao@linaro.org

Previously the 64 bit Neon code had hard coded constants in the setup macro
for YUV conversion, while 32 bit Neon code supported the yuvconstants
parameter.

This change accepts the constants passed to the YUV conversion row function,
allowing different color spaces to be respected - naming JPEG and BT.709.
As well as the existing BT.601.

914a9856c7 Reimplement NV21ToARGB to allow different color matrix. 
Low level for NV21ToARGB written to accept yuv matrix used by
other YUV to ARGB functions.
Previously NV21 was implemented for Windows using NV12 with a different
matrix that swapped U and V.  But the Arm version of the low level does
not allow the matrix U and V contributions to be swapped.
Using a new low level function that reads NV21 and uses the same
yuvconstants as other YUV conversion functions allows an Arm port of
this function.

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.

b2a6af1be6 Change rectangle low level functions to use more conventional row functions including 'any' variations. Previously the yuv function SetPlane stored 32 bit values. Now a more conventional memset() style function is used for YUV that stores bytes. On Haswell a rep stosb is used for YUV. Overall benefit of this CL is improved performance for 'any' width, and simpler row assembly instead of full image assembly. Previously ARGBRect used a low level function that supported a rectangle in assembly. Now it uses a row function, and relies on row coalesce to combine into a single low level call.
