Subject: [PATCH] x86: Compile AVX2 tests with -mno-avx512f

Compile AVX2 tests, which expect AVX2 instructions, with -mno-avx512f to
avoid failures like

FAIL: gcc.target/i386/avx2-vpor-1.c scan-assembler vpor[ \\t]+[^\n]*%ymm[0-9]

when AVX512 is enabled by default.

	PR testsuite/126923
	* gcc.target/i386/avx2-vbroadcastsi128-1.c (dg-options): Add
	-mno-avx512f.
	* gcc.target/i386/avx2-vbroadcastss_ps256-1.c (dg-options):
	Likewise.
	* gcc.target/i386/avx2-vextracti128-1.c (dg-options): Likewise.
	* gcc.target/i386/avx2-vinserti128-1.c (dg-options): Likewise.
	* gcc.target/i386/avx2-vpand-1.c (dg-options): Likewise.
	* gcc.target/i386/avx2-vpand-3.c (dg-options): Likewise.
	* gcc.target/i386/avx2-vpandn-1.c (dg-options): Likewise.
	* gcc.target/i386/avx2-vpor-1.c (dg-options): Likewise.
	* gcc.target/i386/avx2-vpxor-1.c (dg-options): Likewise.
