Merge pull request #5434 from eddyb/rustup 
rustup: update for the new Ty::walk interface.

The first commit fixes a portability bug in `setup-toolchain.sh`, while the second rewrites the handling of "trait impl methods" in `use_self` - even if `Ty::walk` could've still been used, it was IMO a misuse.

This could also serve as a PSA: *please* use `hir_ty_to_ty` instead of trying to compare `hir::Ty`s between themselves or against semantic `Ty`s. Its "quasi-deprecation" is 3 years old and doesn't really mean anything, just that it's currently uncached and that we should eventually querify it (either for a single HIR node, or for all of the nodes in an entire definition).

91d8a804d3 result_map_or_into_option: add lint to catch manually adpating Result -> Option 
Result<T, E> has an `ok()` method that adapts a Result<T,E> into an Option<T>.
It's possible to get around this adapter by writing Result<T,E>.map_or(None, Some).

This lint is implemented as a new variant of the existing
[`option_map_none` lint](https://github.com/rust-lang/rust-clippy/pull/2128)

useless Rc<Rc<T>>, Rc<Box<T>>, Rc<&T>, Box<&T>

refers to  #2394

changelog: Add lints for Rc<Rc<T>> and Rc<Box<T>> and Rc<&T>, Box<&T>

this is based on top of another change #5310 so probably should go after that one.
