* Lazily compute signature type predicates * Use an instance of IdentifierTypePredicate to represent an unresolved type predicate * Simplify `getMaybeTypePredicate` * Invert representation of `resolvedTypePredicate` * Remove `__unresolvedTypePredicate` type and remember to use `noTypePredicate` instead of `undefined` when in all `createSignature` calls * Fix style of getTypePredicateOfSignature * Use in createGetSymbolWalker * Fix bugs for unions of type predicates * Code review * Make noTypePredicate purely an implementation detail of getTypePredictateOfSignature * Add test * Add test for #19642 * Add test with reversed order
