    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: âasmâ 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.
