The max height is currently documented as 16; the max difference per pixel is 255, and a .8h element can easily contain 16*255, thus keep accumulating in two .8h vectors, and just do the final accumulationat the end. This should work for heights up to 256. This requires a minor register renumbering in ff_pix_abs16_xy2_neon.
