We can end up with a rule that has a protocol symbol on the right hand side:
X.Y.Z => X.W.[P]
This will occur if X.W.[P] was obtained by simplifying a term X.W.U.V via
a rule (U.V => [P]), and before completion discovers a rule
(X.W.[P] => X.W).
Fixes rdar://problem/94854326, rdar://problem/94980084.
