virCPUUpdate check the CPU definition for features that were marked as removed in the specified CPU model and explicitly adds those that were not mentioned in the definition. So far such features were added with VIR_CPU_FEATURE_DISABLE policy, but the caller may want to use a different policy in some situations, which is now possible via the removedPolicy parameter.
