(mark_functions_to_output): Also accept bodies for functions with clones. (output_in_order): Skip external vars. * lto-cgraph.c (lto_output_node): External functions are never in other partition. (lto_output_varpool_node): Likewise. * lto-streamer-out.c (lto_write_tree): Always use error_mark_nodes for forgotten initializers. * ipa.c (process_references): Handle external vars. (symtab_remove_unreachable_nodes): Update to handle external vars. (varpool_externally_visible_p): External vars are externally visible. * gimple-fold.c (can_refer_decl_in_current_unit_p): Update. * varpool.c (varpool_remove_node): Remove constructor. (decide_is_variable_needed): Handle externals. (varpool_remove_unreferenced_decls): Likewise. * lto-partition.c (add_references_to_partition): Handle external vars. (partition_varpool_node_p): Likewise. (lto_promote_cross_file_statics): Do not promote externals.
