* 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.
