Although nonescaping closures are representationally trivial pointers to their on-stack context, it is useful to model them as borrowing their captures, which allows for checking correct use of move-only values across the closure, and lets us model the lifetime dependence between a closure and its captures without an ad-hoc web of `mark_dependence` instructions. During ownership elimination, We eliminate copy/destroy_value instructions and end the partial_apply's lifetime with an explicit dealloc_stack as before, for compatibility with existing IRGen and non-OSSA aware passes.
