This changes `Destroy` to use an interface for its implementation. Note that this change includes a lot of test updates. Even when `Destroy` is a no-op, it still causes code generation as part of determining that. Originally I was trying to use ranges to cut down the scope of this, and to a degree I think they have. But a flipside here is that cases where no destructors should be generated -- particularly globals -- would be needed to completely remove destructor calls. Even for ranges, the range can often include the destructor placement. So I've shifted frame-of-thought a little: accept a bunch of destructor churn, because destructors are needed and will be prevalent. The verbosity is a feature of the design to make desugaring apparent in IR, not a bug.
