Subject: [PATCH] x86: Compile AVX256 unaligned load/store tests with
 -mno-avx512f

Compile AVX256 unaligned load/store tests, which expect AVX instructions,
with -mno-avx512f to avoid failures like

FAIL: gcc.target/i386/avx256-unaligned-load-3.c scan-assembler vinsertf128

when AVX512 is enabled by default.

	PR testsuite/126923
	* gcc.target/i386/avx256-unaligned-load-1.c (dg-options): Add
	-mno-avx512f.
	* gcc.target/i386/avx256-unaligned-load-2.c (dg-options): Likewise.
	* gcc.target/i386/avx256-unaligned-load-3.c (dg-options): Likewise.
	* gcc.target/i386/avx256-unaligned-store-1.c (dg-options): Likewise.
	* gcc.target/i386/avx256-unaligned-store-2.c (dg-options): Likewise.
