I can re-write this method to avoid using language address space:

```
  llvm::Optional<LangAS> getConstantAddressSpace() const override {
    return getLangASFromTargetAS(1);
  }
```

Does it look okay to you?

I don't think we need a language guard here as this hook is already guarded by users. E.g. https://github.com/llvm/llvm-project/blob/main/clang/lib/CodeGen/CodeGenModule.cpp#L4137-L4159.
Adding language guards for `TargetInfo::getConstantAddressSpace` method will require API change similar to `adjust` method i.e. explicit `LangOptions` type parameter.
