[heap] Make it clear that mementos are only created for young objects

Mementos should only be created for young allocations. Callers seem to
only pass allocation sites for young allocations right now but there's
no safety net.

This CL just branches the memento creation on the allocation type,
implementing the disired semantics independent from what the callers
pass along.
