[New-bugs-announce] [issue28194] Clean up some checks in dict implementation

[Xiang Zhang]

New submission from Xiang Zhang:

The proposed patch cleans up some unnecessary parts in dict implementation especially NULL checks in lookup functions. There are four states a DictKeyEntry can be. Only in unused(empty) and dummy states me_key can be NULL. So NULL checks in used and pending states are not needed.
