--- Comment #17 from Marc Poulhiès <dkm at gcc dot gnu.org> ---
FWIW, can confirm the above fix works for the small reproducer (x86_64-linux)

   /* Bail out if the representative is BLKmode as we will not be able to
      vectorize this.  */
-  if (TYPE_MODE (TREE_TYPE (rep_decl)) == E_BLKmode)
+  if (!is_gimple_reg_type (TREE_TYPE (rep_decl)))
     return NULL_TREE;
