Motivations for doing it inside DMD instead of a separate library:

- DMD frontend isn't stable (AST nodes are often changed)
- DMD frontend isn't SemVer-tagged (so you can only rely on 
~master)
- people expressed a lot of interest in this being integrated 
directly
- easier bootstrapping (though not really a concern if we require 
the generated headers to be checked into the dmd repository)
