clippy::never_loop has false positive with break from labeled blocks

[Calvin304]

Summary

clippy::never_loop is triggering on a loop with a break to a labeled block. i couldnt seem to get a false positive for nested loops with break statements, so its probably a bug specifically with rfc#2046 (stabalized in 1.65).

Lint Name

never_loop

Reproducer

I tried this code:

fn main() {
    for _ in 0..10 {
        'block: {
            break 'block;
            return;
        }
        println!("looped");
    }
}

I saw this happen:

error: this loop never actually loops
  --> src/main.rs:4:5
   |
4  | /     for _ in 0..10 {
5  | |         'block: {
6  | |             break 'block;
7  | |             return;
8  | |         }
9  | |         println!("looped");
10 | |     }
   | |_____^

This is in spite of this loop looping 10 times when run.
