Well, movdi2sse post-reload splitter won't have any chance with:

 else if (memory_operand (operands[1], DImode))
   {
     rtx tmp = gen_reg_rtx (V2DImode);
     emit_insn (gen_vec_concatv2di (tmp, operands[1], const0_rtx));
     emit_move_insn (operands[0], gen_lowpart (V4SImode, tmp));
   }

So, it is invalid to generate pseudo after reload.
