	* sem_attr.adb (Analyze_Attribute): Attributes 'Old and 'Result
	can now apply to a refined postcondition.
	* sem_ch6.adb (Analyze_Subprogram_Contract): Remove local
	variable Result_Seen. Add variables Case_Prag, Post_Prag,
	Seen_In_Case and Seen_In_Post. Update the mechanism that detects
	whether postconditions and/or constract-cases mention attribute
	'Result and introduce a post-state when applied to functions.
	(Check_Result_And_Post_State): Removed.
	* sem_prag.adb (Analyze_Pragma): Add local variable
	Result_Seen. Verify that the expression of pragma Refined_Post
	mentions attribute 'Result and introduces a post-state.
