Do not propose to remove `async move` if variables are captured by ref
Fixes#10482
changelog: FP [`redundant_async_block`] Do not propose to remove `async move` if variables are captured by ref
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.
r? types
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.
Issue function modifiers in the right order in manual_async_fn lint
Fixes#10450
changelog: [`manual_async_fn`] output function modifiers in correct order
fix `almost_swapped`: Ignore external macros
Fixes#10421 ; Related to #10499 (Fixing points *1* and *3* from #10421)
changelog: [`almost_swapped`]: Add a check to ignore external macros
Fix `almost_swapped` false positive (`let mut a = b; a = a`)
Fixes `2` in #10421
changelog: [`almost_swapped`]: Fix false positive when a variable is changed to itself. (`a = a`)
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.)
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.
enhance [`ifs_same_cond`] to warn same immutable method calls as well

Improve diagnostic of `no_mangle_with_rust_abi`
fixes#10409
Pending rust-lang/rustfmt#5701
This rewords the message to focus on the error being an implicit ABI, rather than the `Rust` ABI. Also downgrades the suggestion to `MaybeIncorrect` and changes the suggestion span to better highlight the change.

Directly construct Inherited in typeck.
Using `InheritedBuilder` + a closure does not seem necessary any more.
+ a few opportunistic simplifications to typeck entry point.
Migrate `write.rs` to `rustc_ast::FormatArgs`
changelog: none
Part 1 of #10233
The additions to `clippy_utils` are the main novelty of this PR, there's no removals yet since other parts still rely on `FormatArgsExpn`
The changes to `write.rs` itself are relatively straightforward this time around, as there's no lints in it that rely on type checking format params
r? `@flip1995`
Include async functions in the len_without_is_empty
fixes#7232
Changes done to the functionality:
Allowing different error types for the functions was disallowed. So the following was linted before but is not after this change
```
impl Foo {
pub len(&self) -> Result<usize, Error1> { todo!(); }
pub is_empty(&self) -> Result<bool, Error2> { todo!(); }
}
```

[arithmetic_side_effects] Fix#10252Fix#10252
At least for integers, shifts are already handled by the compiler.
----
changelog: [`arithmetic_side_effects`]: No longer lints on right or left shifts with constant integers, as the compiler warns about them.
