Intel-SIG: commit f8df91e7 ("x86/cpufeatures: Add macros for Intel's new fast rep string features")

-------------------------------------

KVM_GET_SUPPORTED_CPUID should reflect these host CPUID bits. The bits
are already cached in word 12. Give the bits X86_FEATURE names, so
that they can be easily referenced. Hide these bits from
/proc/cpuinfo, since the host kernel makes no use of them at present.
