The assert fires because the loop only has an infinite loop which
causes the has_loops flag to be cleared. But because a NeverBranch is
also added to the graph on the next pass of loop opts (for
verification), C2 finds a loop and that's inconsistent with the
has_loops flag. This is supposed to be handled by the
only_has_infinite_loops() call in the assert but not in this case
because the loop is not an innermost loop.
