* Replace variables inside | patterns in the if let: let v = if let V::A(v) | V::B(v) = v { v } else ...
* Support nested patterns: let v = if let Ok(Ok(Ok(v))) = v { v } else ...
* Support tuple structs with more than one arg: let v = V::W(v, _) = v { v } else ...
* Correctly handle .. in tuple struct patterns: let v = V::X(v, ..) = v { v } else ...

Extend `trait_duplication_in_bounds` to cover trait objects
This PR extends `trait_duplication_in_bounds` to cover trait objects.
Currently,
```rs
fn foo(_a: &(dyn Any + Send + Send)) {}
```
generates no warnings. With this PR, it will complain about a duplicate trait and can remove it
Moved from rust-lang/rust#110991

Fixes#10609: Adds lint to detect construction of unit struct using `default`
Using `default` to construct a unit struct increases code complexity and adds a function call. This can be avoided by simply removing the call to `default` and simply construct by name.

Fix `items_after_test_module`: Ignore imported modules
Fixes#10713. It does a little bit of dark magic, but intention is what really counts.
changelog:[`items_after_test_module`]: Ignore imported modules (`mod foo;`) with no body.
Using `default` to construct a unit struct increases code complexity and
adds a function call. This can be avoided by simply removing the call to
`default` and simply construct by name.
Add configuration for `semicolon_block` lints
Does exactly what it says on the tin, suggests moving a block's final semicolon inside if it's multiline and outside if it's singleline.
I don't really like how this is implemented so I'm not too sure if this is ready yet. Alas, it might be ok.
