84e42fb363 Auto merge of #10484 - Alexendoo:format-args-ast-2, r=Manishearth
Migrate `format_args.rs` to `rustc_ast::FormatArgs`

changelog: none

Part of https://github.com/rust-lang/rust-clippy/issues/10233

Empty precision specifiers are no longer linted as the span for that isn't present in [`FormatOptions`](https://doc.rust-lang.org/nightly/nightly-rustc/rustc_ast/format/struct.FormatOptions.html)

```rust
format!("{:.}", ...)
```

That could be fixed later with some hackery or a change upstream

2493be2196 Improve is_range_full implementation
Make this function work with signed integer types by extracting the
underlying type and finding the min and max values.

Change the signature to make it more consistent:
- The range is now given as an `Expr` in order to extract the type
- The container's path is now passed, and only as an `Option` so that
  the function can be called in the general case without a container

New lint: detect unnecessary struct building

Fixes #10476.

Running this lint on the top 500 crates produced one hit (in `rust-lang/rust-bindgen`) and [a PR has been submitted there](https://github.com/rust-lang/rust-bindgen/pull/2440).

be01b983c4 Auto merge of #10533 - Nilstrieb:cache, r=dswij
Significantly optimize `significant_drop_tightening`

The lint is very slow as it doesn't cache the deeply nested check for the attribute. If we cache it, we can reduce the time spent on checking `rustc_borrowck` from 28s to 9s, which is a nice improvement. In the profile, the time inside `has_sig_drop_attr` goes from 66% to 0.2%, which is a lot more reasonable.

6db2d5989f Auto merge of #109119 - lcnr:trait-system-cleanup, r=compiler-errors
a general type system cleanup

removes the helper functions `traits::fully_solve_X` as they add more complexity then they are worth. It's confusing which of these helpers should be used in which context.

changes the way we deal with overflow to always add depth in `evaluate_predicates_recursively`. It may make sense to actually fully transition to not have `recursion_depth` on obligations but that's probably a bit too much for this PR.

also removes some other small - and imo unnecessary - helpers.

728ee6f8cd Really dogfood clippy
The dogfood success condition was inverted in `tests/dogfood.rs`:

```rust
  assert!(!failed_packages.is_empty(), …);
```

while instead the `failed_packages` collection must be empty:

```rust
  assert!(failed_packages.is_empty(), …);
```

And indeed, several clippy lint source files were not clean and had to be
fixed in the process.

5924b46543 Fix documentation for derived_hash_with_manual_eq
The documentation retained "vice versa" from the previous incarnation of
the lint but the lint itself no longer lints against manual `Hash`
implementations with a derived `PartialEq`.

I also adjusted the documentation for `PartialOrd`-`Ord` lint as "vice
versa" seemed a little confusing to me there (as to what it was refering
to exactly.)

491f63214a Auto merge of #104833 - Swatinem:async-identity-future, r=compiler-errors
Remove `identity_future` indirection

This was previously needed because the indirection used to hide some unexplained lifetime errors, which it turned out were related to the `min_choice` algorithm.

Removing the indirection also solves a couple of cycle errors, large moves and makes async blocks support the `#[track_caller]`annotation.

Fixes https://github.com/rust-lang/rust/issues/104826.
