Implements CPUInfo.NumCore() and CPUInfo.NumPhysicalCPU()

May be it needs more tests using sample from https://github.com/randombit/cpuinfo/tree/master/x86
What do you mean? Looking at the cpuinfo file, it's a 1 core Xeon with 8 logical processors for hyper-threading. So ``NumCore()`` and ``NumPhysicalCPU() are supposed to return 1 and ``Processors`` 8.
