Regression involving "is not a logical operator" in match

[dtolnay]

The following used to work from rust 1.0.0 through 1.41.0, but has been failing to compile since 1.42.0. I believe the "`and` is not a logical operator" diagnostic is being overzealous and should not be triggering on this program.

mod or {
    pub const ID: usize = 0;
}

mod and {
    pub const ID: usize = 1;
}

fn main() {
    match 0 {
        or::ID => {}
        and::ID => {}
        _ => {}
    }
}

error: `and` is not a logical operator
  --> src/main.rs:12:9
   |
12 |         and::ID => {}
   |         ^^^ help: use `&&` to perform logical conjunction
   |
   = note: unlike in e.g., python and PHP, `&&` and `||` are used for logical operators

Likely introduced in #66994.
