Zuxy Meng ec6c89c1bb avcodec/x86/h264_intrapred: SSE2 impl. of pred8x8l_dc_8
Deprecate MMX. Remove the SSSE3 impl. since we no longer use palignr.
The SSE2 impl. uses several more instructions but is slightly faster.

pred8x8l_dc_8_mmxext:                                   20.5 ( 1.66x)
pred8x8l_dc_8_ssse3:                                    17.9 ( 1.90x)
pred8x8l_dc_8_sse2:                                     15.9 ( 2.15x)
