Found this while auditing uses of `object_id` in `ruby/ruby`. Pulled out from ruby/ruby#9276. This PR replaces look-ups into an Array by `object_id`s, with an identity Set (see [`Set#compare_by_identity`](https://ruby-doc.org/3.2.2/stdlibs/set/Set.html#method-i-compare_by_identity)). This has...

Splitting up `AssertTests.swift` to improve compilation time
