Include only stuff you need, part 4: ast, scopes + fallout.

Rebuilding (after touching certain files) is crazy slow because
includes are out of control.

Fixing it:
- Don't include stuff in headers unless necessary.
- Include the stuff you need, not some other stuff that happens to include the
 stuff you need.
