Fixes #40313 . I have changed the message from contains interior mutability to may contain interior mutability for the following example

use std::cell::Cell;
use std::panic::catch_unwind;
fn main() {
    let mut x = Cell::new(22);
    catch_unwind(|| { x.set(23); });
}

which has been added as a ui test.

Also, the message here and it's respective compile-fail test have been modified.

@gaurikholkar If you reword your PR description slightly so it contains "fixes #40313" then when this PR is merged, GitHub will close the issue automatically.

cc @alexcrichton I think this test is fine, but the name should probably containref-unwind-safe.

@gaurikholkar I meant the description which currently contains "This is a fix to #40313 .", not the title, sorry.

LGTM. I'm waiting for @alexcrichton to hear about the RefUnwindSafe trait.

Sorry what about the RefUnwindSafe trait? I'm not sure what my input is requested on here...

This PR rewords the error message when that trait is not implemented and adds a test for it. Do you have any objections to that? Also, what should the test be named?

Nah seems fine to me! I have no opinions on test naming.

Changing error message from `contains interior mutability` to `may contain interior mutability`

Fixes rust-lang#40313 . I have changed the message from `contains interior mutability` to `may contain interior mutability` for the following example

use std::panic::catch_unwind;
fn main() {
    let mut x = Cell::new(22);
    catch_unwind(|| { x.set(23); });
}
```
which has been added as a ui test.

Also, the message [here](https://github.com/gaurikholkar/rust/blob/master/src/librustc_mir/transform/qualify_consts.rs#L666) and it's respective `compile-fail` test have been modified.
