    gcc.target/i386/pr84876.c: Compile with -mno-avx512f
    
    Compile gcc.target/i386/pr84876.c with -mno-avx512f to disable xmm16-xm31
    registers to get the expected error:
    
    ../gcc.target/i386/pr84876.c:6:3: error: ‘asm’ operand has impossible constraints or there are not enough registers
    
    when AVX512F is enabled by default.
    
            PR testsuite/126923
            * gcc.target/i386/pr84876.c (dg-options): Add -mno-avx512f.
