----------------
Since we are using "llvm::StringRef" here, why not use its split functionality? 
Something like:
```
bool done = false;
while (!done) {
  auto pair = str.split('\n');
  auto len = pair.first.size();
  done = pair.second.empty();
  // Include newline if we are not done
  if (!done)
    ++len; 
  stream.Write(pair.first.data(), 
}
```

This approach also avoids the issue amccarth mentioned below about not ending 
with a newline. It is also quite a bit simpler to follow.

+  } else {
+    stream.PutCString(str);
+  }
----------------
llvm::StringRef can contain NULLs right? Maybe use

```
stream.Write(data, size);
```
