Store HIR attributes in a side table
Same idea as #72015 but for attributes.
The objective is to reduce incr-comp invalidations due to modified attributes.
Notably, those due to modified doc comments.
Implementation:
- collect attributes during AST->HIR lowering, in `LocalDefId -> ItemLocalId -> &[Attributes]` nested tables;
- access the attributes through a `hir_owner_attrs` query;
- local refactorings to use this access;
- remove `attrs` from HIR data structures one-by-one.
Change in behaviour:
- the HIR visitor traverses all attributes at once instead of parent-by-parent;
- attribute arrays are sometimes duplicated: for statements and variant constructors;
- as a consequence, attributes are marked as used after unused-attribute lint emission to avoid duplicate lints.
~~Current bug: the lint level is not correctly applied in `std::backtrace_rs`, triggering an unused attribute warning on `#![no_std]`. I welcome suggestions.~~
Set Clippy authors to "The Rust Clippy Developers"
Clippy has grown enough, that putting specific people in the "authors"
field isn't warranted anymore.
As a heads-up: `@Manishearth` `@llogiq` `@birkenfeld` `@mcarton` `@oli-obk` `@phansch` `@matthiaskrgr` your names will be removed from one or more of the `Cargo.toml` files of Clippy. This of course does not mean that we value your previous work on Clippy any less ❤️
As per our discussion in today's meeting: https://rust-lang.zulipchat.com/#narrow/stream/257328-clippy/topic/Meeting.202021-03-09/near/229502514

This updates all places where match branches check on StatementKind or UseContext.
This doesn't properly implement them, but adds TODOs where they are, and also adds some best
guesses to what they should be in some cases.
Fix ICE 6840 - make is_normalizable more strict

make `is_normalizable` more strict, which should catch this ICE and related cases

Refactor casts lint
Ref: #6724
Changes:
1. Separate the `casts` group from the `types` group.
2. Reorganize the lints of the `casts` group into their own modules.
Notes:
1. I didn't `fix` #6874 in order to maintain this PR as small as possible.

or-patterns: disallow in `let` bindings
~~Blocked on https://github.com/rust-lang/rust/pull/81869~~
Disallows top-level or-patterns before type ascription. We want to reserve this syntactic space for possible future generalized type ascription.

Refactor types lints
Ref #6724.
As described in #6724, `types.rs` contains many groups inside it.
In this PR, I reorganize the lints of the `types` group into their own modules.
