@eddyb suggested that the #[rustc_layout] attribute (usage example) should be improved to replace -Z print-type-sizes and then be used for these tests. Then the tests also would not have to be ignore-pass any more.
That attribute also seems very useful when working with LayoutDetails in general in Rust, I would have loved to know about its existence. I wonder what would be a good place to document it?
