These functions convert between planar and interleaved ARGB,
optionally fill 255 to alpha / discard alpha.
This can help handle YUV(A) with Identity matrix, which is
basically planar ARGB.

Some processors support both MSA and MMI.
when they are enabled together, MSA will be preferd.
This patch move MSA initialization after MMI, so that
MSA can overide MMI and be setted to effective.

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:

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.

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.
