Regardless, I tried this out locally by debugging the `count` tool and this already reported a bunch of errors that would have otherwise gone unnoticed. I haven't looked at them in detail but these were all things I've never seen before.

FWIW, it is possible to serialize an llvm::Error (for example, using llvm::formatv) without consuming it. (I think it did not exist  back when this macro was written) It would just require some refactoring of the macro...
