[opened-archetype] When registering values, do not assert on seeing the same definition twice.
[opened-archetype] When registering values, do not assert on seeing the same definition twice.

Do assert though if we see a different definition.

This allows for one to use the same opened archetype tracker to gather dependent
types from multiple instructions safely. Previously, any overlap would result in
this assert firing.
