Hmm, it seems that we use this for non-template member functions of 
template classes as well; I wonder when that happened.  I guess we 
should update the comment to reflect reality.  And perhaps the name of 
the function, though I lean slightly toward leaving that alone.

I don't think we need a new parameter; just pass the FIELD_DECL into 
maybe_end_member_template_processing and adjust it appropriately.

Also, call m_e_m_t_p from cp_parser_late_parsing_nsdmi rather than 
cp_parser_class_specifier_1.
