…compiler-errors miri: also detect aliasing of in-place argument and return place This is a follow-up to rust-lang#145585 where I forgot to deal with the case of the return place aliasing an in-place argument -- as `@Amanieu` mentioned in rust-lang#71117 (comment), that case must also be forbidden. r? `@compiler-errors`
