* lto-symtab.c (lto_symtab_resolve_symbols): Preffer decl with constructor
over decl without.
* cgraph.c (cgraph_remove_node): Clear also body of unanalyzed nodes.
* cgraph.h (varpool_can_remove_if_no_refs): Handle external correctly.
* cgraphunit.c (process_function_and_variable_attributes): Finalize
extrnal decls.
(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.
