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;
}
```

This switches from text-based search to running the parser to avoid false positives. Inspired by how [rustdoc](3f3250500f/src/librustdoc/test.rs (L366)
