This patch is a truly horrid idea, as it eliminates the error checking
the compiler is trying to provide, and does so globally not only in the
trouble spots.
If I were trying to get rid of this warning, I'd be wondering why
ReplNodeTag is a distinct enum in the first place. Surely it does not
make sense to be using the Node mechanisms on something that isn't
conforming to the standard node numbering. If these nodes ever got
passed to anything else in the system, they'd get misinterpreted.
So I'm inclined to think that clang has pointed out a real issue,
rather than something we ought to paper over.
