The { resolution.single_imports.remove(); } code block does not modify the binding of this resolution. Therefore, the result of resolution.binding() before and after let t = f(self, resolution) will remain the same, and it will always satisfy the result: _ if old_binding.is_some() => return t or None => return t.

And then we delete the update_resolution function because it only called once.

Could you inline the only remaining use of update_resolution as well?

refactor(resolve): delete update_resolution function

The `{ resolution.single_imports.remove(); }` code block does not modify the `binding` of this `resolution`. Therefore, the result of `resolution.binding()` before and after `let t = f(self, resolution)` will remain the same, and it will always satisfy the result: `_ if old_binding.is_some() => return t` or `None => return t`.

And then we delete the `update_resolution` function because it only called once.

Revert rust-lang#112758 and add test case

Fixes rust-lang#112831.

Cannot unwrap `update_resolution` for `resolution.single_imports.remove(&Interned::new_unchecked(import));` because there is a relationship between the `Import` and `&NameBinding` in `NameResolution`. This issue caused by my unfamiliarity with the data structure and I apologize for it.

This PR had been reverted, and test case have been added.
