Hmm, it is unfortunate that we need a lookup here. I think it would not be too
hard to add a `getValue` or similar operation to the key iterator. But
alternatively we could do something like `llvm::zip(IdentifierTable->keys(),
IdentifierTable->data())` to avoid this lookup and have a pair of iterators.
