If neither of those, I'd still be interested to know any further details that have turned up - the details so far have narrowed things down a bit, but still haven't gotten me close to figuring out what state the IR would need to be in to trigger this error.

Good news. With this rebased reapply commit (https://github.com/MaskRay/llvm-project/commit/18eaa15964c2857d666fea0409cbb90e8818ee95), I can no longer reproduce the crash ...
Perhaps just reland this...
