Correct restriction of vm_compute when handling universe polymorphic
definitions. Instead of failing with an anomaly when trying to do conversion or computation with the vm's, consider polymorphic constants as being opaque and keep instances around. This way the code is still correct but (obviously) incomplete for polymorphic definitions and we avoid introducing an anomaly. The patch does nothing clever, it only keeps around instances with constants/inductives and compile constant bodies only for non-polymorphic definitions.
