…on time from the constant itself Make definitional Skolem constants aware of their introduction time (removes need for caches) and formalizes the notion of definitional formerly known as small constants. Definitional Skolem constants are smaller then most terms in termordering. A PR with a rework of term orderings is coming "A skolem constant was created while a taclet application was instantiated, so its name and its introduction time depended on when the strategy considered the application, not on when the proof used it, and the introduction time had to be remembered in a cache of its own. The constant now carries its kind and the number of rule applications the goal had performed when it was created, and the goal creates the constants when it applies the rule. The function kind also distinguishes the constants a definition introduces, which the term ordering can then place below the term they name." (created with AI tooling support)

As mentioned at the devloper meeting. This is the first PR of three cleaning up the AI supported work.
Make definitional Skolem constants aware of their introduction time (removes need for caches) and
formalizes the notion of definitional formerly known as small constants. Definitional Skolem constants
are smaller then most terms in termordering.
Speeds up Skolem heavy proof by up to 10% bet, 5% on the whole runAllFunProof collection.
