    libstdc++: Fix pretty printer lookup for class templates [PR122812]

    Under some circumstances the type.name of a pair<> type starts with
    "struct". This confuses GDB when we use gdb.lookup_type for the name of
    template specialization using "struct pair<...>" in its template
    argument list.

    Using type.tag avoids this problem.

    libstdc++-v3/ChangeLog:

            PR libstdc++/122812
            * python/libstdcxx/v6/printers.py (lookup_templ_spec): Use
            gdb.Type.tag if present.
