Yes, you are right. In this case, the code sneaks in through a
RECORD_TYPE which contains the TEMPLATE_DECL in its maxval field,
because that's where C++ stores TYPE_METHODS.
I don't really see any need for us to handle TEMPLATE_DECL outside of
the C++ FE, so I'm tempted to just totally ignore language codes when
we see them in output_tree(). I will go with this for now. On the
way in, we simply ignore the field.
