Hi, this the third patch of GFNI ISASET enabling. It enables GF2P8AFFINE 
instruction, described here:

gcc/
        * config/i386/gfniintrin.h (_mm_gf2p8affine_epi64_epi8, 
_mm256_gf2p8affine_epi64_epi8,
        (_mm_mask_gf2p8affine_epi64_epi8, _mm_maskz_gf2p8affine_epi64_epi8,
        _mm256_mask_gf2p8affine_epi64_epi8, _mm256_maskz_gf2p8affine_epi64_epi8,
        _mm512_mask_gf2p8affine_epi64_epi8, _mm512_maskz_gf2p8affine_epi64_epi8,
        _mm512_gf2p8affine_epi64_epi8): New intrinsics.
        * config/i386/i386-builtin.def (__builtin_ia32_vgf2p8affineqb_v64qi,
        __builtin_ia32_vgf2p8affineqb_v32qi, 
__builtin_ia32_vgf2p8affineqb_v16qi): New builtins.
        * config/i386/sse.md (vgf2p8affineqb_*): New pattern.

gcc/testsuite/
        * gcc.target/i386/avx-1.c: Handle new intrinsics.
        * gcc.target/i386/avx512f-gf2p8affineqb-2.c: New runtime tests.
        * gcc.target/i386/avx512vl-gf2p8affineqb-2.c: Ditto.
        * gcc.target/i386/gfni-1.c: Add tests for GF2P8AFFINE.
        * gcc.target/i386/gfni-2.c: Ditto. 
        * gcc.target/i386/gfni-3.c: Ditto. 
        * gcc.target/i386/gfni-4.c: Ditto.
        * gcc.target/i386/sse-13.c: Handle new tests.
        * gcc.target/i386/sse-23.c: Handle new tests.

Ok for trunk?

Thanks,
