They're compile-time assertions failures, so they should theoretically be reproducible in a non-JIT environment, but I've been unable to do so thus far. If someone with access to that bot could lend some insight on how to reproduce the failures with llc on a non-ARM host, I would be most appreciative.

OK, cool. It'll be nice to get this bot back to green. It has a tendency to find things that others don't. I would still like to be better able to reproduce this sort of thing locally, though. Bug-fixing via educated guesswork is no fun.
