    libstdc++: Remove std_ratio_t_tuple
    
    This removes the std_ratio_t_tuple function from the Python
    pretty-printer code.  It is not used.  Apparently the relevant parts
    were moved to StdChronoDurationPrinter._ratio at some point in the
    past.
    
    libstdc++-v3/ChangeLog:
    
            * python/libstdcxx/v6/printers.py (std_ratio_t_tuple):
            Remove.
