(lto_symtab_merge_cgraph_nodes): Use lto_symtab_symbol_p.
(lto_symtab_prevailing_decl): Get int sync with lto_symtab_symbol_p.
* varpool.c (dump_varpool_node): Dump more flags.
* lto-partition.c (get_symbol_class): Fix weakrefs.
(lto_balanced_map): Fix weakrefs.
(privatize_symbol_name): Remove unnecesary label.
(rename_statics): Handle weakrefs as statics.
* gcc.dg/lto/attr-weakref-1_0.c: New testcase.
