----------------
I don't quite understand your comment from the previous patch:

> This is really just moved from TransferTest.cpp -- and it's more closely related to the `runDataflow()` functions there and in the newly added RecordOps.cpp. (I can't call it `runDataflow()` because then it would differ only in return type from one of the functions in the overload set.)

I don't see another `checkDataflow()` function with the same signature. Furthermore, `checkDataflow()` overloads above already return an `llvm::Error`.
