Unneeded multiple pattern with wildcard

[ghost]

Any multiple patterns with the wildcard pattern can be removed as the wildcard will match anyway

match "foo" {
    "a" => {
        dbg!("matched a");
    }
    "bar" | _ => {
        dbg!("bar or wildcat");
    }
}

Should be written as

match "foo" {
    "a" => {
        dbg!("matched a");
    }
    _ => {
        dbg!("matched (bar or) wildcard");
    }
}

In which file do we need to change this?

[ghost]

looking at this PR #1273 , I guess clippy_lints/src/copies.rs

[flip1995]

I'd recommend to put this in clippy_lints/src/matches.rs
