Reviewers: Kasper Lund, Message: There's lots of cheesiness here, but it's simple and works.
We should figure out a way to enforce it (in other words, catch failures early) in debug builds. The default argument is annoying, but fits the bill. Description: Experimental: introduce a simple mechanism to allow jump targets with backward control flows to indicate at their binding site that only the topmost N elements need to be mergable. Aliasing and constants lower in the frame will be as expected based on the forward control flows. Use the mechanism for deferred code snippets, which all fit the simple mechanism.
