Introduce templates to loop queries looking for singletons.

Several loop queries look for a singleton by finding all instances and then
returning whether there is 1 instance or not.  This can be improved by
stopping the search after 2 have been found.  Introduce templates for
these functions to special-case such usage.

There is no intended functional change.
