	(TYPE_SYMTAB_IS_DIE): Define.
	(struct tree_type): Change GTY for symtab field to use
	TYPE_SYMTAB_IS_ADDRESS and friends and to use a debug_hooks field
	to pick the union field.
	* debug.h (struct gcc_debug_hooks): Add tree_type_symtab_field.
	(dump_go_spec_init): Declare.
	* toplev.c (process_options): Handle flag_dump_go_spec.

	* vmsdbgout.c (vmsdbg_debug_hooks): Likewise.
	* sdbout.c (sdb_debug_hooks): Likewise.  Do not define if
	SDB_DEBUGGING_INFO is not defined.
	* doc/invoke.texi (Option Summary): Mention -fdump-go-spec.
	(Overall Options): Document -fdump-go-spec.
	* Makefile.in (OBJS-common): Add godump.o.
	(debug.o): Add dependency on $(TREE_H).
	(godump.o): New target.
