Jieyou Xu b38a86f4d7 Revert "Rollup merge of #122661 - estebank:assert-macro-span, r=petrochenkov"

This reverts commit 1eeb8e8b15, reversing
changes made to 324bf2b9fd.

Unfortunately the assert desugaring change is not backwards compatible,
see RUST-145770.

Code such as

```rust
#[derive(Debug)]
struct F {
    data: bool
}

impl std::ops::Not for F {
  type Output = bool;
  fn not(self) -> Self::Output { !self.data }
}

fn main() {
  let f = F { data: true };

  assert!(f);
}
```

would be broken by the assert desugaring change. We may need to land
the change over an edition boundary, or limit the editions that the
desugaring change impacts.
