KVM: selftests: Test the PMU event "Instructions retired"
Add testing for the event "Instructions retired" (0xc0) in the PMU event filter on both Intel and AMD to ensure that the event doesn't count when it is disallowed. Unlike most of the other events, the event "Instructions retired" will be incremented by KVM when an instruction is emulated. Test that this case is being properly handled and that KVM doesn't increment the counter when that event is disallowed.
