unhelpful error when match pattern upper bound literal is converted to less than lower bound

[tspiteri]

pub fn foo(u: u8) {
    match u {
        255...256 => {}
        _ => {}
    }
}

This triggers error E0030, and the error message states that the lower bound is larger than the upper bound, presumably because 256 is converted to 0u8. The overflowing_literals warning could have hinted at the real issue, but the error takes precedence and the root cause is thus not highlighted.

Closing in favor of #68972.
