I guess some customized parsing/printing code needs to be written before it could be used.

Thanks for tying this!

You are right this probably needs a custom parser/printer a bit similar to `LLVM_DIParameter`. Unfortunately the current infrastructure does not provide a nice way to implement such sum types. Let's land as is then.
