never_loop misses continue stmt inside let..else terminator

[yotamofek]

Summary

Seems like the never_loop lint ignores any continue statements that are inside the else blocks in let..else statements. This produces a false positive.

Lint Name

never_loop

Reproducer

I tried this code:

#![feature(let_else)]

fn test(a: Option<usize>) {
    loop {
        // doesn't trigger lint:
        // if let Some(a) = a {
        let Some(a) = a else {
            continue;
        };

        break;
    }
}

I saw this happen:

error: this loop never actually loops
  --> src/lib.rs:6:5
   |
6  | /     loop {
7  | |         // doesn't trigger lint: if let Some(a) = a {
8  | |         let Some(a) = a else {
9  | |             continue;
...  |
14 | |         break;
15 | |     }

   = note: `#[deny(clippy::never_loop)]` on by default

I expected to see this happen:
never_loop should not be triggered.
