NEON optimized bilinear sampling
Adds NEON version of interpolate_4_pixels used by smooth upscaling, and
bilinear sampling.
The SSE2 version is reordered to match the NEON version so they have
the same order of operations and a faster version that loads directly
into vector registers.
Testing is extended so we have a test of smoothness that can catch more
possible mistakes.
