[issue33554] Optimize PyDictObject

2018-05-17 Thread b@n 

b@n  added the comment:

A little performance optimization, but I think the key is not in performance 
optimization.
The semantics of the dictresize function are not uniform, and it is 
inconvenient for others to read. The dictresize function should be split to 
make it just resize. What do you think?
