Its not built by default so I could't really check, but looking through the file that included it, I couldn't prove it was being used.

Indeed, I had the same question myself...

I couldn't find a particular way to use the enum otherwise myself, but I'm not an expert of the relevant code. `MCOperandInfo` does have a member that is somewhat misleadingly named `OperandType`, but that one seems to refer to `llvm::MCOI::OperandType` rather than this enum.
