Make it clearer that a type or lifetime argument not being used can be fixed by referencing it in a struct's fields, not just using `PhathomData`.

This commit improves the suggestions provided when function parameters do not have types: - A new suggestion is added for arbitrary self types, which suggests adding `self: ` before the type. - Existing suggestions are now provided when a `<` is found where a `:` was expected (previously only `,` and `)` or trait items), this gives suggestions in the case where the unnamed parameter type is generic in a free function. - The suggestion that a type name be provided (e.g. `fn foo(HashMap<u32>)` -> `fn foo(HashMap: TypeName<u32>)`) will no longer occur when a `<` was found instead of `:`. - The ident will not be used for recovery when a `<` was found instead of `:`.

Implement Clone::clone_from for LinkedList See rust-lang#28481. This represents a substantial speedup when the list sizes are comparable, and shouldn't ever be significantly worse. Technically split_off is doing an unnecessary search, but the code is hopefully cleaner as a result. I'm happy to rework anything that needs to be changed as well!

@withoutboats

…houtboats BacktraceStatus: add Eq impl See discussion on rust-lang#53487. --- Is adding `Copy` too ambitious? It's a "status", so I don't forsee any non-POD data that might go in there, but it would restrict future variants more than `Eq` does. Cc: @withoutboats @abonander

@petrochenkov

…trochenkov Filter out RLS output directories on tidy runs Closes rust-lang#64957 r? @petrochenkov

…rn-inference, r=cramertj extract expected return type for async fn generators Fixes rust-lang#60424 cc @Centril, I know you've been eager to see this fixed. r? @cramertj

Compare `primary` with maximum of `children`s' line num instead of dropping it Fix rust-lang#65001.
