SGTM, I'd like to add more detail but I don't think we can fit it all in an assert; optionally, a comment line above to the effect of "Verify we have the right format, see `LLVMIsNewDbgInfoFormat`" or such. Worth demonstrating extra caution here, since we're potentially impacting people who're disconnected from the RemoveDI work.
