21be9122aa libyuv:loongson optimize compare/row/scale/rotate files with mmi. 
Currently, libyuv supports MIPS SIMD Arch(MSA),
but libyuv does not supports MultiMedia Instruction(MMI)(such as loongson3a platform).

In order to improve performance of libyuv on loongson3a platform,
this provides optimize 98 functions with mmi.

2ed2402fa0 I420ToI010 for 8 to 10 bit YUV conversion. 
Convert planar 8 bit formats to planar 16 bit formats.

Includes msan fix for Convert8To16Row_Opt unittest.

I420 is YUV bt.601 8 bits per channel with 420 subsampling.
I010 is YUV bt.601 10 bits per channel with 420 subsampling.
I is color space - bt.601.  The function does no color space
 conversion so H420ToI010 is aliased to this function as well.
0 = 420 subsampling.  The chroma channels are half width / height.
10 = 10 bits per channel, stored in low 10 bits of 16 bit samples.

For SSSE3 version:
out/Release/libyuv_unittest --gtest_filter=*LibYUVConvertTest.I420ToI010_Opt --libyuv_width=1280 --libyuv_height=720 --libyuv_repeat=999 --libyuv_flags=-1 --libyuv_cpu_info=-1

Regarding performance measurement, We have created standalone tests which pass in row's data from a 1920x1080 filled buffer to both the C and MSA functions. And such N iterations are executed to get more accurate timings of C vs MSA.

f553db2d30 HalfFloatPlane unittest for denormal half floats 
Halffloats have a limited range.  It shouldnt normally come up, but if the scale value passed in produces a small value, the half floats will be denormals, which are slow and/or flust to zero.  This test ensures they behave the same in C and SIMD and tests the performance of denormals.

bea690b3e0 AVX2 YUV alpha blender and improved unittests 
AVX2 version can process 16 pixels at a time for improved memory bandwidth and fewer instructions.

unittests improved to test unaligned memory, and test exactness when alpha is 0 or 255.

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.

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.
