Optimize performance of copy.deepcopy by adding a fast path for atomic types

[eendebakpt]

Feature or enhancement

Proposal:

The performance of copy.deepcopy can be improved by adding a fast path for the atomic types. This will reduce the overhead of checking the memo and the overhead of calling the dispatch method from the deepcopy dispatch table.

Has this already been discussed elsewhere?
