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.
