I think the patch is ok.
If in the future we want to handle those other loops, we will need to compute
the loop bound in add_loop_constraints() with a check for whether the stmt is
dominated by the exit or not.
Here is what we do today for all stmts in the loop:
tree nb_iters = number_of_latch_executions (loop);
if (TREE_CODE (nb_iters) == INTEGER_CST)
{
/* loop_i <= cst_nb_iters */
the constraint '<=' on statements' iteration domains implies that the loop
should be under a do-while form.
