This enables the same warnings that are enabled in `clippy_lints` also
in `clippy_utils` and `clippy_dev`. Then it makes sure, that the
`deny-warnings` feature is passed down to `clippy_lints` and
`clippy_utils` when compiling Clippy.
Fix FPs about generic args
Fix 2 false positives in [`use_self`] and [`useless_conversion`] lints, by taking into account generic args and comparing them.
Fixes: #7205Fixes: #7206
changelog: Fix FPs about generic args in [`use_self`] and [`useless_conversion`] lints
* Suggest `&mut iter` when the iterator is used after the loop.
* Suggest `&mut iter` when the iterator is a field in a struct.
* Don't lint when the iterator is a field in a struct, and the struct is
used in the loop.
* Lint when the loop is nested in another loop, but suggest `&mut iter`
unless the iterator is from a local declared inside the loop.
`implicit_return` improvements
fixes: #6940
changelog: Fix `implicit_return` suggestion for async functions
changelog: Improve `implicit_return` suggestions when returning the result of a macro
changelog: Check for `break` expressions inside a loop which are then implicitly returned
changelog: Allow all diverging functions in `implicit_return`, not just panic functions
Better suggestions when returning macro calls.
Suggest changeing all the break expressions in a loop, not just the final statement.
Don't lint divergent functions.
Don't suggest returning the result of any divergent fuction.
Add lint to check for boolean comparison in assert macro calls
This PR adds a lint to check if an assert macro is using a boolean as "comparison value". For example:
```rust
assert_eq!("a".is_empty(), false);
```
Could be rewritten as:
```rust
assert!(!"a".is_empty());
```
PS: The dev guidelines are amazing. Thanks a lot for writing them!
changelog: Add `bool_assert_comparison` lint
Fixing FPs for the `branches_sharing_code` lint
Fixes#7053Fixes#7054
And an additional CSS adjustment to support dark mode for every inline code. It currently only works in paragraphs, which was an oversight on my part 😅. [Current Example](https://rust-lang.github.io/rust-clippy/master/index.html#blacklisted_name)
This also includes ~50 lines of doc comments and is therefor not as big as the changes would indicate. 🐧

All of these bugs were introduced in this dev version and are therefor not worth a change log entry.

cc: `@camsteffen` since you have a pretty good overview of the `SpanlessEq` implementation 🙃
Improve `map_entry` suggestion
fixes: #5176fixes: #4674fixes: #4664fixes: #1450
Still need to handle the value returned by `insert` correctly.
changelog: Improve `map_entry` suggestion. Will now suggest `or_insert`, `insert_with` or `match _.entry(_)` as appopriate.
changelog: Fix `map_entry` false positives where the entry api can't be used. e.g. when the map is used for multiple things.
Fix false positives where the map is used before inserting into the map.
Fix false positives where two insertions happen.
Suggest using `if let Entry::Vacant(e) = _.entry(_)` when `or_insert` might be a semantic change
Fix a FP in `missing_const_for_fn`
where a function that calls a standard library function whose constness
is unstable is considered as being able to be a const function. Fixes#5995.
The core change is the move from `rustc_mir::const_eval::is_min_const_fn` to `rustc_mir::const_eval::is_const_fn`. I'm not clear about the difference in their purpose between them so I'm not sure if it's acceptable to call `qualify_min_const_fn::is_min_const_fn` this way now.

changelog: `missing_const_for_fn`: No longer lints when an unstably const function is called
Invalid null usage v2
This is continuation of #6192 after inactivity.
I plan to move paths into the compiler as diagnostic items after this is merged.
