that code won't build - did you mean :

       if (!standard_sse_constant_p (vec_cst, V2DImode))
-       vec_cst = validize_mem (force_const_mem (V2DImode, vec_cst));
+       {
+         start_sequence ();
+         vec_cst = validize_mem (force_const_mem (V2DImode, vec_cst));
+         rtx_insn *seq = get_insns ();
+         end_sequence ();
+         emit_insn_before (seq, insn);
+       }
