x86: Don't hardcode the height to 8 in sad8_xy2_mmx The height is hardcoded in some of the me_cmp functions, but not in all of them. But in the case of all other functions, it's hardcoded in the same place in SIMD functions as in the C reference functions, while this one function differs from the behaviour of the C code. (Before 542765ce3eccbca587d54262a512cbdb1407230d, there were a couple other sad8_*_mmx functions with similar hardcoded height.)
