Summary

0022094: Speeding-up Standard_GUID::HashCode()

Description

It happened so that the method Standard_GUID::HashCode() is a very very popular
method! It is widely used in OCAF for storage of presentation, function and
other drivers, for example.
As I noticed, the method is frequently called for the same GUID. This
improvement implements an idea to cache the hash code calculated for the
previous call of the method if the "Upper" and the GUID are equal.
