The mmx function performs two registers in parallel;
given the larger register size of SSE2, the same amount
of data can be processed in one register with some speedups.
(Given that this function is used for tail-processing,
not processing more data is important.)
Switching to SSE2 also fixes a bug introduced in
554c2bc708: Since said
commit, only half the dither values were used. This
seems not to matter in practice, as the functions here
use dither only in the following form:
((filtersize-1)*8+dither)>>4. The dither values used
here come from ff_dither_8x8_128 which has the property
that ff_dither_8x8_128[i][j] and ff_dither_8x8_128[i][j+4]
always lead to the same result in the above formula.
