  /* As a last resort, trying using a gather load or scatter store.

     ??? Although the code can handle all group sizes correctly,
     it probably isn't a win to use separate strided accesses based
     on nearby locations.  Or, even if it's a win over scalar code,
     it might not be a win over vectorizing at a lower VF, if that
     allows us to use contiguous accesses.  */
