    libstdc++: [_GLIBCXX_INLINE_VERSION] Add gdb pretty print for _GLIBCXX_DEBUG
    
    In _GLIBCXX_DEBUG mode containers are in std::__debug namespace but not template
    parameters. In _GLIBCXX_INLINE_VERSION mode most types are in std::__8 namespace but
    not std::__debug containers. We need to register specific type printers for this
    combination.
    
    libstdc++-v3/ChangeLog:
    
            * python/libstdcxx/v6/printers.py (add_one_template_type_printer): Register
            printer for types in std::__debug namespace with template parameters in std::__8
            namespace.
