The previous fix checked `isEvaluated` on the term in a sort predicate before applying rules. This is correct but leads to too many fall-backs which slow down symbolic execution when sort predicates are used in rewrite side conditions. The only case that matters is when an _unevaluated function_ is at the _head_ of the term in the sort predicate. This is now matched directly.

There was a problem hiding this comment.
Also modified the logging to include the term with function head, for easier debugging

Seems to be working now, and no negative impact on KEVM proofs.

isEvaluatedon the term in a sort predicate before applying rules. This is correct but leads to too many fall-backs which slow down symbolic execution when sort predicates are used in rewrite side conditions. The only case that matters is when an unevaluated function is at the head of the term in the sort predicate. This is now matched directly.
