I disagree.  Such a function doesn't make any sense and shouldn't exist.
You can't tell at runtime whether an iterator_range is singular for the
same reasons that you can't tell whether an iterator is singular.  If
iterator_range didn't have any constructors that allowed you to pass
iterators, it would be a different matter.
