rollup merge of #23780: ruud-v-a/wrapping

Browse Source 
This allows `Wrapping<T>` to be used in `assert_eq!`, for example.

One of the tests (compile-fail/xc-private-method.rs) fails, but I can hardly imagine it is related to this change. I would also like to add a tests to ensure that `assert_eq!` compiles and keeps working in the future for `Wrapped<T>` values, but there appear to be no tests in libcore. What would be a good place to add such a test?
