InterpolateRow_SME and InterpolateRow_16_SME need special cases to
handle if source_y_fraction is 256 since this would overflow a byte and
can just be a call to memcpy instead.
InterpolateRow_16To8_SME is never called with a source_y_fraction value
of 256 so there is no need for a special case here.
