        * config/i386/i386-builtin.def
        (__builtin_ia32_vgf2p8affineinvqb_v64qi,
        __builtin_ia32_vgf2p8affineqb_v64qi, __builtin_ia32_vgf2p8mulb_v64qi):
        Require also OPTION_MASK_ISA_AVX512F in addition to
        OPTION_MASK_ISA_GFNI.
        (__builtin_ia32_vgf2p8affineinvqb_v16qi_mask,
        __builtin_ia32_vgf2p8affineqb_v16qi_mask): Require
        OPTION_MASK_ISA_AVX512VL instead of OPTION_MASK_ISA_SSE in addition
        to OPTION_MASK_ISA_GFNI.
        (__builtin_ia32_vgf2p8mulb_v32qi_mask): Require
        OPTION_MASK_ISA_AVX512VL in addition to OPTION_MASK_ISA_GFNI and
        OPTION_MASK_ISA_AVX512BW.
        (__builtin_ia32_vgf2p8mulb_v16qi_mask): Require
        OPTION_MASK_ISA_AVX512VL instead of OPTION_MASK_ISA_AVX512BW in
        addition to OPTION_MASK_ISA_GFNI.
        (__builtin_ia32_vgf2p8affineinvqb_v16qi,
        __builtin_ia32_vgf2p8affineqb_v16qi, __builtin_ia32_vgf2p8mulb_v16qi):
        Require OPTION_MASK_ISA_SSE2 instead of OPTION_MASK_ISA_SSE in addition
        to OPTION_MASK_ISA_GFNI.
        * config/i386/i386.c (def_builtin): Change to builtin isa/isa2 being
        a requirement for all ISAs rather than any of them with a few
        exceptions.
        (ix86_add_new_builtins): Clear OPTION_MASK_ISA_64BIT from isa before
        processing.
        (ix86_expand_builtin): Require all ISAs from builtin's isa and isa2
        bitmasks to be enabled with 3 exceptions, instead of requiring any
        enabled ISA with lots of exceptions.
        * config/i386/sse.md (vgf2p8affineinvqb_<mode><mask_name>,
        vgf2p8affineqb_<mode><mask_name>, vgf2p8mulb_<mode><mask_name>):
        Change avx512bw in isa attribute to avx512f.
        * config/i386/sgxintrin.h: Add license boilerplate.
        * config/i386/vaesintrin.h: Likewise.  Fix macro spelling __AVX512F
        to __AVX512F__ and __AVX512VL to __AVX512VL__.
        (_mm256_aesdec_epi128, _mm256_aesdeclast_epi128, _mm256_aesenc_epi128,
        _mm256_aesenclast_epi128): Enable temporarily avx if __AVX__ is not
        defined.
        * config/i386/gfniintrin.h (_mm_gf2p8mul_epi8,
        _mm_gf2p8affineinv_epi64_epi8, _mm_gf2p8affine_epi64_epi8): Enable
        temporarily sse2 rather than sse if not enabled already.

        * gcc.target/i386/sse-26.c: New test.
