@dkolsen-pgi  Great PR!
Since it touches functions returning `!void` or `!cir.void`, I made some changes recently with https://github.com/llvm/clangir/commit/568b51537e573c7a8fb616cda5cdd0aa54bc0832 to avoid disrupting some MLIR invariants.
Are you up-streaming the changes in commit order or are you up-streaming the changes with the latest version of a feature?
@joker-eph How to up-stream some changes which are cross-project like https://github.com/llvm/clangir/pull/1203 which introduces a new MLIR parser/pretty-printer feature like:

https://github.com/llvm/clangir/pull/1203/files#diff-6c1c134d749d53cf770548806b955401e47b1f15ffe084905a0b132d73b0b1fe

to allow some keywords starting with `!`?
