We can refer to it as vector::reference instead, which always works. That fixes some compilation errors in debug mode, but the tests fail at run-time instead because the printers for vector helpers are only registered for the std namespace, not std::__cxx1998. That is fixed by using add_container to register the printers instead of add_version, as the former registers them in the std and std::__cxx1998 namespaces.

(build_libstdcxx_dictionary): Register printers for vector types in debug mode too. * testsuite/libstdc++-prettyprinters/simple.cc: Adjust expected output for invalid _Bit_reference.
