    libstdc++: Remove unused locals from printers.py
    
    flake8 pointed out some unused local variables in the libstdc++
    pretty-printers.  This removes them.
    
    libstdc++-v3/ChangeLog:
    
            * python/libstdcxx/v6/printers.py
            (StdExpOptionalPrinter.__init__, lookup_node_type):
            Remove unused variables.
