	OPTION_MASK_ISA_AVX512VL in addition to OPTION_MASK_ISA_GFNI and
	OPTION_MASK_ISA_AVX512BW.
	(__builtin_ia32_vgf2p8mulb_v16qi_mask): Require

	__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.
