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.

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.
