Add builtin_expect to predict that CPU supports cpuid to cpuid.h
This is needed to avoid impossible threading update in vectorizer testcase,
but should also reflect reality on most CPUs we care about.
gcc/ChangeLog:
* config/i386/cpuid.h (__get_cpuid_count, __get_cpuid_max): Add
__builtin_expect that CPU likely supports cpuid.
