Here's a patch. You might want to change the beginning to include the full
path to clangVisualizers.txt. I would've done this myself but I have no idea
where will this file end up inside the source tree :)

Added visualizer for StringRef (assumes null terminated string which I know
isn't the case always, but I don't think there's a way around this)
