There's a FieldParser implementation above that's the old-style bit enum. It's handled by always quoting bit enum values that have more than one bit set.

Usually, these FieldParser values were very much unused, as there are separate parser implementatinos both in `EnumParameter` and in other bits of `mlir-tblgen` that mean this code was basically never called.
