This may need wider support, specifically we may need to generate an accessor function in .h.inc/.cpp.inc.  Something like https://github.com/llvm/llvm-project/blob/main/mlir/tools/mlir-tblgen/OpDefinitionsGen.cpp#L1204, for example.

I'm wary about making this kind of change in a widely shared file.  Maybe we could just handle this in OmpOpGen.cpp?  Specifically, infer this information in there based on the type of the attribute?
