    Make dump_ranger routines externally visible.
    
    There was an inline extern declaration for dump_ranger that was a bit of
    a hack.  I've removed it in favor of an actual prototype.  There are
    also some trivial changes to the dumping code in the path solver.
    
    gcc/ChangeLog:
    
            * gimple-range-path.cc (path_range_query::path_range_query): Add
            header.
            (path_range_query::dump): Remove extern declaration of dump_ranger.
            * gimple-range-trace.cc (dump_ranger): Add DEBUG_FUNCTION marker.
            * gimple-range-trace.h (dump_ranger): Add prototype.
