  Log:
    parse.y: resurrect before pindown
    
    * parse.y (rb_pin_dynamic_symbol): resurrect the dynamic symbol
      which may be unmarked already and swept at next time, before
      pindown.
    
    * parse.y (dsym_node_gen): now rb_intern_str() resurrects dynamic
      symbols, via lookup_sym_id() and rb_pin_dynamic_symbol().
