[PATCH v8 03/12] perf/x86/intel/pt: Add new bit definitions for Intel PT MSRs

[Luwei Kang <luwei.kang@intel.com>]

These bit definitions are use for emulate MSRs read/write
for KVM. For example, IA32_RTIT_CTL.FabricEn[bit 6] is available
only when CPUID.(EAX=14H, ECX=0):ECX[bit 3] = 1. If KVM guest
try to set this bit with CPUID.(EAX=14H, ECX=0):ECX[bit3] = 0
a #GP would be injected to KVM guest.
