// This is a phase for testing. It behaves like a register allocator in the sense that it
// eliminates temporaries from the program. It accomplishes this by always spilling all
// temporaries. The resulting code is going to be very inefficient. This phase is great if you
// think that there is a bug in the register allocator. You can confirm this by running this
// phase instead of the register allocator.
//
// Note that even though this phase does the cheapest thing possible, it's not even written in a
// particularly efficient way. So, don't get any ideas about using this phase to reduce compiler
// latency. If you wanted to do that, you should come up with a clever algorithm instead of using
// this silly thing.
