KVM: x86: Advertise fast REP string features inherent to the CPU
Fast zero-length REP MOVSB, fast short REP STOSB, and fast short REP
{CMPSB,SCASB} are inherent features of the processor that cannot be
hidden by the hypervisor. When these features are present on the host,
enumerate them in KVM_GET_SUPPORTED_CPUID.
