Fix incorrect coroutines codegen behavior

If all the suspension calls in a suspend function were "hidden"
under the for-convention (iterator/next/hasNext) calls,
control-flow didn't find them, thus supposing that there is no
suspension points and there is no need to generate a coroutine state machine

The solution is to add relevant calls to CFG
