	* sem_prag.adb (Analyze_Refined_Depends_In_Decl_Part): Adapt checking
	for optional refinement of abstract state with partial
	visible refinement.
	(Analyze_Refined_Global_In_Decl_Part): Adapt checking for optional
	refinement of abstract state with partial visible refinement. Implement
	new rules in SPARK RM 7.2.4 related to optional refinement.
