References within Rc/Arc may not be meaningful

What it does

The reference to Sized within Rc/Arc may not make sense,
consider moving the value into Arc?

Advantage

• Perhaps unnecessary Arc can be avoided

Drawbacks

No response

Example

use std::{rc::Rc, sync::Arc};

fn main() {
    let n = 2;
    let mut m = 3;
    let _x = Arc::new(&n);
    let _y = Rc::new(&mut m);
}

Could be written as:

use std::{rc::Rc, sync::Arc};

fn main() {
    let n = 2;
    let mut m = 3;
    let _x = Arc::new(n);
    let _y = Rc::new(m);
}

Start by examining the Rc and Arc examples in the issue and determine what behavior is proposed for references to Sized values. Clarify whether the intended result is a new lint and what conditions would make moving the value into Rc or Arc safe and complete.
