0ab75c37b6 Auto merge of #5977 - xvschneider:AddLintPanicInResult, r=matthiaskrgr
Add lint panic in result

### Change
Adding a new "restriction" lint that will emit a warning when using "panic", "unimplemented" or "unreachable" in a function of type option/result.

### Motivation
Some codebases must avoid crashes at all costs, and hence functions of type option/result must return an error instead of crashing.

### Test plan
Running:
TESTNAME=panic_in_result cargo uitest ---

4972989b61 Add a lint for an async block/closure that yields a type that is itself awaitable.
This catches bugs of the form

tokio::spawn(async move {
    let f = some_async_thing();
    f // Oh no I forgot to await f so that work will never complete.
});

4f4abf4e06 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;
}

126790999a new lint: Returning unit from closures expecting Ord
This lint catches cases where the last statement of a closure expecting
an instance of Ord has a trailing semi-colon. It compiles since the
closure ends up return () which also implements Ord but causes
unexpected results in cases such as sort_by_key.

Fixes #5080

reprise: rebase, update and address all concerns
