    c++: fix cxx_print_type's template-info dumping
    
    Unlike DECL_TEMPLATE_INFO which is stored in DECL_LANG_SPECIFIC,
    TYPE_TEMPLATE_INFO isn't stored in TYPE_LANG_SPECIFIC, so we don't
    need to check for both in cxx_print_type.  This fixes dumping the
    template-info of ENUMERAL_TYPE and BOUND_TEMPLATE_TEMPLATE_PARM,
    which seem to never have TYPE_LANG_SPECIFIC.
    
    gcc/cp/ChangeLog:
    
            * ptree.cc (cxx_print_type): Remove TYPE_LANG_SPECIFIC
            test guarding TYPE_TEMPLATE_INFO.
