--- Comment #2 from David Malcolm <dmalcolm at gcc dot gnu.org> ---
Presumably we should simply strip the location from arg, though there are some
places with:

  /* Call get_element_number to validate arg1 if it is a constant.  */
  if (TREE_CODE (arg1) == INTEGER_CST)
    (void) get_element_number (TREE_TYPE (arg0), arg1);

which suggests any such stripping needs to happen there.
