Fix POPCNT detection gcc compile error

Browse Source 
Also don't use __cpuid() intrinsic for Intel under
Linux because gives wrong results when detecting HT,
use the gcc version instead. Finally clean up the code.

Error was due to changed __cpuid() signature for
gcc compiler.

No functional change.
