`invalid_upcast_comparisons` wrongly unmangled macros

[profetia]

Summary

invalid_upcast_comparisons wrongly showed macro definition instead of invocation.

Reproducer

I tried this code:

macro_rules! add_one {
    ($x:expr) => {
        $x + 1
    };
}

let x: u8 = 1;
(add_one!(x) as u32) > 300;

I expected to see this happen:

error: because of the numeric bounds on `add_one!(x)` prior to casting, this expression is always false
  --> src/main.rs:13:5
   |
13 |     (add_one!(x) as u32) > 300;
   |     ^^^^^^^^^^^^^^^^^^^^^^^^^^
   |
