Fix an issue while detection Core topology on Core 2 CPU.
...
Some CPU like Intel Yorkfield (Core 2 Quad) reports max CPUID > 0xB but doesn't support CPUID = 0xB. Check x2apic flag to be sure CPUID 0xB is supported. If not, fallback to older detection method

Solve an issue with Core 2 Duo/Quad and same gen CPUs, where HTT flag is enabled in CPUID while the CPU does not support SMT. ( #125 #129 )
...
Now compare the number of physical core with the number of reserved APIC to check if SMT is really available or not

Add AP Enumeration to distinguish P-Core from E-Core on Hybrid CPUs ( #62 )
...
Add AP Enumeration to distinguish E-Core from P-Core on Intel Hybrid CPUs, and exclude them from the selected cores by default. Including E-Cores slows down some tests and takes longer to catch memory errors.
A new exclude_ecores flag has been added in config.c to include E-Cores if needed.

Remove distinction between physical and virtual CPUs.
...
This is no longer needed, now we can display as many CPUs as we can
physically handle.
