Do we have anything that enforces the fact that the HoistAllocas pass must be
run before the FlattenCFG pass? @ftynse [gave a

Meeting about an idea for "normal forms" that would be very useful for this
(basically, it would be a mechanism to say "I need the IR to be in this form to
run this pass"), but I think at the time it was only out-of-tree work he had
done. I'm not sure if any of that is in place yet.
