    x86: Add __volatile__ to __cpuid and __cpuid_count

    Since CPUID instruction may return different values on hybrid core.
    volatile is needed on asm statements in <cpuid.h>.

            PR target/99704
            * config/i386/cpuid.h (__cpuid): Add __volatile__.
            (__cpuid_count): Likewise.
