Thanks! I will try to see if we can use it. The problem is we don't have a bsi,
we insert those stmts using bsi_insert_on_edge_immediate on
loop_preheader_edge.

In order to do this, we will have to go through the statement list created by
force_gimple_operand, and I am not sure that it's a good idea.
