Is this some kind of perf optimization?

No. The constants that we are handed could be doing anything, like implementing self.hash method as in this example. If we don't use a compare_by_identity set to store them, then their hash method gets called (among others), which could raise, as it was happening on #1728.
If a constant implements `self.hash`, then Tapioca DSL compiler should be resilient against it.
There have been a few instances where we have not been using `Set`s with `compare_by_identity` properly. This commit fixes those instances so that the test added in the previous commit passes. Fixes #1728
