* Eliminate DECL_FIELD_SIZE.

	* builtins.c (built_in_class_names, built_in_names): New variables.
	* c-decl.c (finish_struct): Set specified size in DECL_SIZE.
	* expr.c (expand_expr, case COMPONENT_REF): Get field size from
	DECL_SIZE, not DECL_FIELD_SIZE.
	* print-tree.c (print_node): Remove code that prints extra blank
	lines in some cases.
	Properly handle inline and builtin function cases.
	* stor-layout.c (layout_decl): Get specified size from DEC_SIZE.
	* tree.h (built_in_class_named, built_in_names): New declarations.
	(union tree_decl): Rename internal unions to u1 and u2 and change
	some of their components.
	Add new field built_in_class.
	(DECL_ALIGN, DECL_INCOMING_RTL, DECL_SAVED_INSNS, DECL_FRAME_SIZE):
	Reflect above changes.
	(DECL_FUNCTION_CODE, DECL_BUILT_IN_CLASS): Likewise.
	(DECL_SET_FUNCTION_CODE, DECL_FIELD_SIZE): Deleted.
	* objc/objc-act.c (objc_copy_list): Use DECL_SIZE, not DECL_FIELD_SIZE.
	(encode_field_decl): Likewise; also remove obsolete test for bitfield.
	* ch/ch-tree.h (DECL_ACTION_NESTING_LEVEL): Use new tree union name.
	* ch/decl.c (finish_struct): Don't clear DECL_FIELD_SIZE.
	* ch/typeck.c (make_chill_struct_type): Likewise.
	(apply_decl_field_layout): General cleanup.
	Set DECL_SIZE instead of DECL_FIELD_SIZE.
	* cp/class.c (build_vtbl_or_vbase_field, check_methods): Don't clear
	DECL_FIELD_SIZE.
	(check_bitfield_decl, check_field_decls): Set DECL_SIZE, not
	DECL_FIELD_SIZE.
	* cp/rtti.c (expand_class_desc): Likewise.
	* cp/cp-tree.h (DECL_INIT_PRIORITY): Use underlying union name.
	(THUNK_VCALL_OFFSET): Likewise.
	(THUNK_DELTA): Reflect changes in ../tree.h.
	* java/java-tree.h (LABEL_PC): Relect name changes in ../tree.h.
	(DECL_BIT_INDEX): Use underlying representation.
	* java/parse.h (DECL_INHERITED_SOURCE_LINE): Likewise.
