avcodec/x86/diracdsp: migrate last remaining MMX function to SSE2
The add_dirac_obmc8_mmx function was the only MMX function left. This
patch migrates it to SSE2.
Here are the checkasm benchmark results:
diracdsp.add_dirac_obmc_8_c: 2299.1 ( 1.00x)
diracdsp.add_dirac_obmc_8_mmx: 237.6 ( 9.68x)
diracdsp.add_dirac_obmc_8_sse2: 109.1 (21.07x)
