Modularity + TASTy serialization issue when compiling modified standard library #20707
Description
I'm running an experiment using the Scala standard library and I was modifying parts of it
to use the new experimental modularity feature (#20061) for annotating where type
parameters should be instantiated with singleton types. But the generated TASTy has
a cyclic reference somewhere so it all blows up.
I've managed to reproduce the issue by adding a new, dummy, class with the modularity Singletons
to the standard library. I'll try to reproduce on a smaller project later, but I'm not familiar with
TASTy serialization myself.

I get a unpickler error followed by a subsequent crash.
