Remove halfpix specialization This function only exists as a shortcut to subpixel variance with predefined offsets. xoffset = 4 for horizontal, yoffset = 4 for vertical and both for "hv" Removing this allows the existing optimizations for the variance functions to be called. Instead of having only sse2 optimizations, this gives sse2, ssse3, msa and neon. BUG=webm:1273 Change-Id: Ieb407b423b91b87d33c4263c6a1ad5e673b0efd6
