    i386: Fix emissing of __builtin_cpu_supports.

            PR target/103661

    gcc/ChangeLog:

            * config/i386/i386-builtins.c (fold_builtin_cpu): Compare to 0
            as API expects that non-zero values are returned (do that
            it mask == 31).
            For "avx512vbmi2" argument, we return now 1 << 31, which is a
            negative integer value.
