(gdb) p debug_generic_expr (treeop2)
{ 0, 0, 0, 0, 4, 4, 4, 4, 8, 8, 8, 8, 12, 12, 12, 12 }
(gdb) p debug_rtx (op0)
(reg:V16QI 173 [ vect__13.7496 ])
$2 = void
(gdb) p debug_rtx (op1)
(reg:V16QI 173 [ vect__13.7496 ])

so it's a quite usual permute.  But possibly we fail to verify we can code-gen
it.
