        PR objc/44140
        * objc-act.c: build_objc_string_decl() remove declaration.
        (finish_var_decl): Remove forcing of var output and marking
        as "Used". 
        (init_def_list): Use integer_zero_node. 
        (init_objc_symtab): Use integer_zero_node, make the short
        integer type specific on relevant nodes.
        (generate_objc_symtab_decl): Remove call to 
        forward_declare_categories().  Use null_pointer_node where
        appropriate.  
        (build_module_descriptor): Comment and mark this item as 
        DECL_PRESERVE_P. 
        (generate_static_references): Use gcc_unreachable instead of
        abort (). 
        (diagnose_missing_method): New.
        (build_next_selector_translation_table): New.
        (build_gnu_selector_translation_table): New.
        (add_objc_string): Merge code from build_objc_string_decl...
        ... and delete build_objc_string_decl().
        (generate_dispatch_table): Make integer types explicit.
        (generate_category): Pass implent and arrange for the data
        to be extracted within the routine.  Do not start new vars, 
        but finish the ones collcted during parsing.
        (generate_shared_structures): Likewise.
        (finish_objc):  Reorder code so that we finish variables before
        referencing them.  Save the global data before calling meta-data
        creation routines, and pass the current reference to the two 
        main routines.  Only call generate_objc_image_info () for the 
        NeXT runtime.
        (generate_classref_translation_entry): Comment on and make this
        item DECL_PRESERVE_P.
        (handle_class_ref): Use varpool interfaces, comment on and make
        this item DECL_PRESERVE_P.
        (handle_impent): Likewise.
        (generate_objc_image_info): Only generate when the content is 
        non-zero.  Make integer types explict.
