[Bug c/16119] In C language diagnostic messages, %E should but cannot display general expressions

Close but not quite right, a bogus ({anonymous}) appears.
In c-objc-common.c the suspect code is:

    case 'E':
      if (TREE_CODE (t) == IDENTIFIER_NODE)
        n = IDENTIFIER_POINTER (t);
      else
        pp_expression (cpp, t);
      break;

I think that should instead be

    case 'E':
      pp_expression (cpp, t);
      return true;
