…nkfelix Fix ICEs when `Self` is used in type aliases I think it is right just to disallow this at resolution stage rather than let typeck produce a cyclic error. This is in line with previous behaviour. There was probably no need at all for the change that introduced this bug in rust-lang#57428, so I've simply reversed it. Fixes rust-lang#62263, rust-lang#62364, rust-lang#62305. r? @eddyb
