Would disabling the assertion that there's a single edge in the EH-frame fixer fix the issue for now?

As a temporary fix I prefer commenting out the assertion. We could land this too, but I suspect we'll want to revert in the future and move to a design where edges support more than one target instead. I _think_ we're gong to want to be able to say "what is _the edge_ at this offset", then inspect the result, rather than parsing a sequence of edges at an offset to understand what's going on. We really need a proper discussion about this though.
