Class inheritance cycles incorrectly/improperly detected

[ArcticLight]

verifyClassChain is doing much the wrongs; for example

class A {}
class B extends A {}
class C extends B {}

reports an illegal cyclic dependency involving B in class C.

Fixed this in 71a83335b74c8ad65810e7e734984bf5e2f36159 as evidenced by the output

I don't know, that seems correct to me...? A class shouldn't be able to extend itself?

I believe this was resolved?
