* config/i386/i386.c (ix86_simd_clone_compute_vecsize_and_simdlen):

	* config/i386/i386.c (ix86_simd_clone_compute_vecsize_and_simdlen):
	Add support for AVX512F clones, include them by default for
	exported OpenMP declare simd functions.  For AVX2 allow simdlen 32
	and use it if charasteric type is 8-bit, for AVX512F allow simdlen
	up to 128.

	* lib/target-supports.exp (check_effective_target_vect_simd_clones):
	Check for avx512f effective targets instead of avx2.
	* gcc.dg/gomp/declare-simd-1.c: Add scan-assembler-times directives
	for AVX512F clones.
	* gcc.dg/gomp/declare-simd-3.c: Likewise.
	* g++.dg/gomp/declare-simd-1.C: Likewise.
	* g++.dg/gomp/declare-simd-3.C: Likewise.
	* g++.dg/gomp/declare-simd-4.C: Likewise.
