Use the cpuid 64 bit flag to pick the default CPU name for an unknown model.
...
For the Family 6 switch in sys::getHostCPUName, an unrecognized model was
reported as "i686". That's a really bad default since it means that new
CPUs will be treated as if they can only use 32-bit code. This just looks
at the cpuid extended feature flag for 64 bit support, and if that is set,
it uses a default x86-64 cpu. Similar logic is already used for the Family
15 code. <rdar://problem/11314502>
