Why go through the hassle of going through a `const char*`? Just use the StringRef directly?

```suggestion
  llvm::StringRef additional_features =
      arch.GetAdditionalDisassemblyFeatureStr();
  // Prepend the additional_features if it's not already in the features_str to
  // avoid duplicates.
  if (additional_features) {
    UpdateFeatureString(additional_features, features_str);
  }
```
