Add test to call all EnumerateInstance{s,Names}, GetInstance, Associators and References.

This simple test calls EnumerateInstances and EnumerateInstanceNames on all
LMI_* classes and then calls GetInstance, AssociatorNames, Associators,
ReferenceNames and References on all instances.

It does not check actual content of returned names and instances, it just
checks that the above calls do not crash and are consistent (e.g.
EnumerateInstanceNames returns the same set as EnumerateInstances).
