[PATCH v9 05/17] x86/cpufeatures: Enumerate MSR_IA32_CORE_CAP

[Fenghua Yu]

MSR_IA32_CORE_CAP (0xcf) contains bits that enumerate some model
specific features.

The MSR 0xcf itself is enumerated by CPUID.(EAX=0x7,ECX=0):EDX[30].
When this CPUID bit is 1, the MSR 0xcf exists.

Detailed information on the CPUID bit and the MSR can be found in the
latest Intel 64 and IA-32 Architectures Software Developer's Manual.
