0031f69999 Auto merge of #8592 - c410-f3r:stuff, r=flip1995 
Do not fire `panic` in a constant environment

Let rustc handle panics in constant environments.

Since https://github.com/rust-lang/rust-clippy/issues/8348 I thought that such modification would require a lot of work but thanks to https://github.com/rust-lang/rust-clippy/pull/8588 I now know that it is not the case.

changelog: [`panic`]: No longer lint in constant context. `rustc` already handles this.

59dd179ad3 Rollup merge of #94309 - eholk:issue-57017, r=tmandry 
[generator_interior] Be more precise with scopes of borrowed places

Previously the generator interior type checking analysis would use the nearest temporary scope as the scope of a borrowed value. This ends up being overly broad for cases such as:

```rust
fn status(_client_status: &Client) -> i16 {
    200
}

fn main() {
    let client = Client;
    let g = move || match status(&client) {
        _status => yield,
    };
    assert_send(g);
}
```

In this case, the borrow `&client` could be considered in scope for the entirety of the `match` expression, meaning it would be viewed as live across the `yield`, therefore making the generator not `Send`.

In most cases, we want to use the enclosing expression as the scope for a borrowed value which will be less than or equal to the nearest temporary scope. This PR changes the analysis to use the enclosing expression as the scope for most borrows, with the exception of borrowed RValues which are true temporary values that should have the temporary scope. There's one further exception where borrows of a copy such as happens in autoref cases also should be ignored despite being RValues.

Joint work with `@nikomatsakis`

Fixes #57017
