For AST dumping, we can kind of do whatever we think makes the most sense. But
we still need AST printing to generate the source code roughly the same as the
user wrote it, so my preference is to print the canonicalized attribute. e.g.,
if we translate `__counted_by(size + 0)` into `__counted_by(size)`, I think
it's fine to print that instead of with the `+ 0` but I'd prefer to see either
form over `__counted_by(this->size)`.
