Add partialeq_to_none lint
Initial implementation of #9275, adding lint `partialeq_to_none`. This is my first time working on `clippy`, so please review carefully.
I'm unsure especially about the `Sugg`, as it covers the entire `BinOp`, instead of just covering one of the sides and the operator (see the multi-line example). I was unsure if pinpointing the suggestion wouldn't be brittle...
changelog: [`PARTIALEQ_TO_NONE`]: Initial commit
`explicit_auto_deref` changes
fixes#9123fixes#9109fixes#9143fixes#9101
This avoid suggesting code which hits a rustc bug. Basically `&{x}` won't use auto-deref if the target type is `Sized`.
changelog: Don't suggest using auto deref for block expressions when the target type is `Sized`
changelog: Include the borrow in the suggestion for `explicit_auto_deref`
changelog: Don't lint `explicit_auto_deref` on `dyn Trait` return
changelog: Don't lint `explicit_auto_deref` when other adjustments are required
changelog: Lint `explicit_auto_deref` in implicit return positions for closures
More proc-macro detection
fixes#6514fixes#8683fixes#6858fixes#6594
This is a more general way of checking if an expression comes from a macro and could be trivially applied to other lints. Ideally this would be fixed in rustc's proc-macro api, but I don't see that happening any time soon.
changelog: FPs: [`unit_arg`] [`default_trait_access`] [`missing_docs_in_private_items`]: No longer trigger in code generated from proc-macros.
move [`assertions_on_result_states`] to restriction
"Backports" the first commit of https://github.com/rust-lang/rust-clippy/pull/9273, so that the lint doesn't go into beta as a warn-by-default lint.
The other changes in the linked PR can ride the train as usual.
r? ``@xFrednet`` (only Clippy changes, so we don't need to bother compiler people)

For Clippy:
changelog: none
Always include a position span in `rustc_parse_format::Argument`
Moves the spans from the `Position` enum to always be included in the `Argument` struct. Doesn't make any changes to use it in rustc, but it will be useful for some upcoming Clippy lints
Fix suggestions for `async` closures in redundant_closure_call
Fixes#9052
changelog: Fix suggestions given by [`redundant_closure_call`] for async closures
- only compare where predicates to trait bounds when generating where
clause specific message to fix#9151
- use comparable_trait_ref to account for trait bound generics to fix#8757
