Re: [PATCH, middle-end]: Fix also PR46292 (was: Fix PR 44569)

> OK, I can revert the patch on branches.

Thanks.

The patch is OK for mainline if you add a comment explaining where these 2 
kinds of CONCATN come from, e.g.:

  /* VECTOR_CSTs in debug expressions are expanded into CONCATN instead of
     regular CONST_VECTORs.  They have vector or integer modes, depending
     on the capabilities of the target.  Cope with them.  */
  if (partmode == VOIDmode && VECTOR_MODE_P (innermode))
    partmode = GET_MODE_INNER (innermode);
  else if (partmode == VOIDmode)
    {
      enum mode_class mclass = GET_MODE_CLASS (innermode);
      partmode = mode_for_size (inner_size * BITS_PER_UNIT, mclass, 0);
    }
