  -----------
  [SLP]Fix a crash trying finding insert point for GEP nodes with non-gep
insts.

If the vectorizable GEP node is built, which should not be scheduled,
and at least one node is a non-gep instruction, need to insert the
vectorized instructions before the last instruction in the list, not
before the first one, otherwise the instructions may be emitted in the
wrong order.
