Andreas Rheinhardt 79080a547a avcodec/x86/h264_chromamc: Use xmm regs in chroma_mc4 SSSE3 functions 
Doubling the register size allowed to avoid two pmaddubsw.
It is also ABI compliant (the old version lacked an emms)
and the average versions no longer rely on padding (the old versions
used pavgb with a memory operand reading eight bytes,
although only four are needed).

Old benchmarks (the latter four refer to RV40):
avg_h264_chroma_mc4_8_c:                               145.7 ( 1.00x)
avg_h264_chroma_mc4_8_ssse3:                            32.3 ( 4.51x)
put_h264_chroma_mc4_8_c:                               136.1 ( 1.00x)
put_h264_chroma_mc4_8_ssse3:                            29.0 ( 4.70x)
avg_chroma_mc4_c:                                      162.1 ( 1.00x)
avg_chroma_mc4_ssse3:                                   31.1 ( 5.22x)
put_chroma_mc4_c:                                      137.5 ( 1.00x)
put_chroma_mc4_ssse3:                                   28.6 ( 4.81x)

New benchmarks:
avg_h264_chroma_mc4_8_c:                               146.7 ( 1.00x)
avg_h264_chroma_mc4_8_ssse3:                            26.5 ( 5.53x)
put_h264_chroma_mc4_8_c:                               136.8 ( 1.00x)
put_h264_chroma_mc4_8_ssse3:                            22.5 ( 6.09x)
avg_chroma_mc4_c:                                      165.5 ( 1.00x)
avg_chroma_mc4_ssse3:                                   27.2 ( 6.08x)
put_chroma_mc4_c:                                      138.1 ( 1.00x)
put_chroma_mc4_ssse3:                                   23.2 ( 5.96x)
