Thank you for working on this.  I think this is the right idea, but I
have two comments:

* In add_builtin_candidates, I think you can just do:

  argtypes[i] = unlowered_expr_type (lvalue_type (args[i]));

* In layout_class_type, I understand that you're trying to preserve
cv-qualification.  I don't see a test case for that, though.  If there's
a bug you're fixing here, let's have a test case for it.

Thanks,
