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.

cf160cdbaa implement I444ToABGR by swapping uv and transpose matrix 
U contributes to B and G.  V contributes to R and G.
By swapping U and V, they contribute to the opposite channels.  Adjust the matrix so the U contribution is in the matrix location such that it till contribute to the
new B channel and vice versa.
This allows ABGR versions of YUV conversion to use the same low level code as ARGB, just using a different matrix and swapping U and V pointers.

As a result the existing I444ToABGRRow functions are no longer needed and are removed.

Previously this function was only Intel AVX2 optimized for Windwos.  Now it is also optimized for Arm and GCC.

ARMv7 Neon
Was LibYUVConvertTest.I444ToABGR_Opt (75971 ms)
Now LibYUVConvertTest.I444ToABGR_Opt (3672 ms)

90335f6043 bug fix for odd width 16/24 bit to i420 
A bug was introduced on arm when the code for 'any' width switch to
a temporary stack buffer and simd.
The C version handles odd width by doing 1 pixel, instead of averaging 2.
But the SIMD any version is supposed to replicate the last pixel, then
the subsampling in Neon will average the pixel with itself, producing
the same result.
The previous version did this, but only for ARGB 32 bit, which was to
avoid introducing issues with subsampled YUY2 source.  This CL adds
replication for RGB 16 bit values.

ba4b409d51 Fix ARGBToI411 odd width bug. 
The any function for handling ARGBToI411 was not handling the pixel
replication correctly.  On 422 and odd width was handled by duplicating
a pixel of source.  411 needs replication for remainders of 1, 2 or 3
pixels.

The C version was handling odd width but with an average of the remainder
pixels, which does not match the SIMD 'any' handling off remainder.
This changes the odd width handling to mimic the any version.
