[Glass] IdentityKeyValueDictionary vs IdentityDictionary?

[Dale Henrichs via Glass]

Reading the class comments of the two classes and poking around in the 
implementation, it looks like IdentityKeyValueDictionary does not use 
associations when adding entries to the dictionary and 
IdentityDictionary creates associations ... so i seems that adding 
entries would always be more expensive for IdentityDictionary...
