Don't cache results of coinductive cycle
Fixes #96319 The logic around handling co-inductive cycles in the evaluation cache is confusing and error prone. Fortunately, a perf run showed that it doesn't actually appear to improve performance, so we can simplify this code (and eliminate a source of ICEs) by just skipping caching the evaluation results for co-inductive cycle participants. This commit makes no changes to any of the other logic around co-inductive cycle handling. Thus, while this commit could potentially expose latent bugs that were being hidden by caching, it should not introduce any new bugs.
