The old C++ pass didn't catch a few cases. Also: * The new pass is significantly simpler: it doesn't perform dataflow for _all_ memory locations at once using bitfields, but handles each store separately. (In both implementations there is a complexity limit in place to avoid quadratic complexity) * The new pass works with OSSA
