Include only stuff you need, part 2: ast.h, ast-value-factory.h in ports.

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.
