Subject: [PATCH] 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().
