Uff, this is super broken. It looks like people are not aware of the fact that this enum must list entries in the same order as https://github.com/llvm/llvm-project/blob/main/llvm/include/llvm/IR/Metadata.def and that it is an append-only list. It looks like stuff like DIAssignID got inserted into the middle of the list :(

I think we should either have Metadata.def explicitly list the ID (like FixedMetadataKinds.def) or else create an explicit mapping operation between the C API enum and the C++ one.
