i386: Don't pass -msse2avx to assembler for -mavx
With
gcc -O2 -fPIC -flto -g -c -o a.o a.c
gcc -O2 -fPIC -flto -g -mavx -c -o b.o b.c
gcc -shared -O2 -fPIC -flto -g -o lib1.so a.o b.o
LTO correctly generates AVX for b.o and SSE for a.o. But the GCC driver
passes -msse2avx to assembler, which encodes SSE instructions as AVX
instructions. We shouldn't pass -msse2avx to assembler for -mavx.
PR target/87522
* config/i386/gnu-user.h (ASM_SPEC): Don't pass -msse2avx to
assembler for -mavx.
* config/i386/gnu-user64.h (ASM_SPEC): Likewise.
