Demangle C++11 ref-qualifier.
* cp-demangle.c (d_ref_qualifier): New.
(d_nested_name, d_function_type): Use it.
(d_parmlist): Don't get confused by a ref-qualifier.
(cplus_demangle_type): Reorder ref-qualifier.
(d_pointer_to_member_type): Likewise.
(d_dump): Handle DEMANGLE_COMPONENT_REFERENCE_THIS and
DEMANGLE_COMPONENT_RVALUE_REFERENCE_THIS.
(d_make_comp, has_return_type, d_encoding): Likewise.
(d_print_comp, d_print_mod_list, d_print_mod): Likewise.
(d_print_function_type, is_ctor_or_dtor): Likewise.
2013-03-27 Kai Tietz <ktietz@redhat.com>
* configure: Regenerated.
