This fixes #15692 and does not seem to break an existing compilation tests. The problem with seen when it comes #15692 is that seen means that type that has repeated types will get a lower size and this incorrectly triggers the divergence check since some of the steps involved less repeated types. The seen logic was introduced in #6329 and the motivation was to deal with F-bounds. Since not tests fail it not clear if this logic is still needed to deal with F-bounds? If it is still needed we can add a test and instead of removing the seen logic we can make it track only types the appear as a bound and could cause infinite recursion instead of tracking all.

Also adds test case that stackoverflows without any seen check. [Cherry-picked 008d58e]
