5b07b9ed61 Widen understanding of prelude import 
Prelude imports are exempt from wildcard import warnings. Until now only
imports of the form

```
use ...::prelude::*;
```

were considered. This change makes it so that the segment `prelude` can
show up anywhere, for instance:

```
use ...::prelude::v1::*;
```

191b0806d2 Capture tokens for Pat used in macro_rules! argument 
This extends PR #73293 to handle patterns (Pat). Unlike expressions,
patterns do not support custom attributes, so we only need to capture
tokens during macro_rules! argument parsing.

Warn about explicit self-assignment

Warn about assignments where left-hand side place expression is the same
as right-hand side value expression. For example, warn about assignment in:

```rust
pub struct Event {
    id: usize,
    x: i32,
    y: i32,
}

pub fn copy_position(a: &mut Event, b: &Event) {
    a.x = b.x;
    a.y = a.y;
}
```

changelog: New lint `self_assignment`, checks for explicit self-assignments.
