Closing the bug as support was implemented a while back. There are some next
steps which would be nice to pursue, let me summarize them:
1) pipe SCEV through LICM and down into MustExecute. This lets us handle much
more complicated cases than the current Constants and SimplifyInstruction
approach.
2) figure out a way to efficiently handle implicit control flow (i.e. handle
cases where potentially faulting instructions only run on the second iteration
down some rare path...) I'd been working on this, but have basically given up
now and approached my original problem from a different angel.
