Replace cpuid asm statement with __cpuid_count
The compiler doesn't know that the cpuid asm statement in intel_check_word
will trash RBX. We are lucky that it doesn't cause any problems since
RBX is also used by compiler for other purposes so that RBX is saved and
restored. This patch replaces it with __cpuid_count.
[BZ #17259]
* sysdeps/x86_64/cacheinfo.c (intel_check_word): Replace cpuid
asm statement with __cpuid_count.
