c-common.h: New file.

	* c-common.h: New file.
	* c-common.c (permanent_obstack): Delete unused declaration.
	(c_global_trees): New array.
	(c_common_nodes_and_builtins): New function; split off common code
	from init_decl_processing in both c-decl.c and cp/decl.c.
	* c-tree.h: Delete lots of declarations of tree nodes; replaced by
	c_global_trees and accessor macros defined in c-common.h.
	Include c-common.h.
	* c-decl.c: Delete definitions for tree nodes that were replaced by
	c_global_trees.
	(init_decl_processing): Build void_list_node.
	Call c_common_nodes_and_builtins; delete code to generate the common
	builtins here.

	* objc/objc-act.c (build_module_descriptor): Rename variable
	void_list_node to avoid clash with c-common.h.

	* cp/cp-tree.h: Delete lots of declarations of tree nodes; replaced by
	c_global_trees and accessor macros defined in c-common.h.
	(cp_tree_index): New enumeration.
	(cp_global_trees): Declare new array.  Add accessor macros for it, and
	delete declarations of tree nodes replaced by it.
	(builtin_function): Delete macro, add declaration for new function.
	Include c-common.h.
	* cp/decl.c: Delete definitions for tree nodes that were replaced by
	cp_global_trees and c_global_trees.
	(init_decl_processing): Call c_common_nodes_and_builtins; delete code
	to generate the common builtins here.
	(builtin_function): New function.
	* cp/decl2.c (abort_fndecl): Delete declaration.
	* cp/except.c (expand_builtin_return_address): Delete declaration.
	(builtin_return_address_fndecl): Delete variable.
	(const_ptr_type_node): Delete declaration.
