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.
