It is for omitting brackets `(` `)` around the single result type. I have copied it from `FunctionType`:
```
    .Case<FunctionType>([&](FunctionType funcTy) {
        os << '(';
        interleaveComma(funcTy.getInputs(), [&](Type ty) { printType(ty); });
        os << ") -> ";
        ArrayRef<Type> results = funcTy.getResults();
        if (results.size() == 1 && !llvm::isa<FunctionType>(results[0])) {
          printType(results[0]);
        } else {
          os << '(';
          interleaveComma(results, [&](Type ty) { printType(ty); });
          os << ')';
        }
      })
```
