----------------
It is odd that these values aren't preserved by the AST writer. I wonder if 
that is intentional.

It took me a while, but I eventually found that these data members are assigned 
via an inclusion of `clang/Driver/Options.inc` somewhere.

Rather than assigning values here, I think we would be better off adding member 
initializers in the class definition. But I think we do need to look into why 
the AST writer isn't preserving the values.
