+	Merged from transactional-memory.
+
+	* cp-demangle.c (cplus_demangle_fill_ctor): Accept
+	gnu_v3_object_ctor_group.
+	(cplus_demangle_fill_dtor): Accept gnu_v3_object_dtor_group.
+	(d_ctor_dtor_name): Recognize gnu_v3_object_ctor_group
+	and gnu_v3_object_dtor_group.
+	(d_dump): Handle DEMANGLE_COMPONENT_TRANSACTION_CLONE
+	and DEMANGLE_COMPONENT_NONTRANSACTION_CLONE.
+	(d_make_comp, d_print_comp): Likewise.
+	(d_special_name): Generate them.
