    lto-dump: modernize a bit
    
    gcc/lto/ChangeLog:
    
            * lto-dump.cc (dump_list): Remove trailing return.
            (dump_symbol): Likewise.
            (dump_body): Filter name based on mangled name.
            (dump_tool_help): Use GIMPLE wording.
            (lto_main): Update wording.
