exp_util.adb, [...] (Entity_Of): Moved to Sem_Util.

2013-10-17  Hristian Kirtchev  <kirtchev@adacore.com>

	* exp_util.adb, exp_util.ads (Entity_Of): Moved to Sem_Util.
	* sem_prag.adb (Analyze_Global_In_Decl_List): Mark a null
	item list as being analyzed.
	(Analyze_Global_List): Mark a
	null global list and multiple global items as being analyzed.
	(Analyze_Input_Item): Check the unit that defines the input
	variable or state, not the reference to it.
	* sem_util.ads, sem_util.adb (Entity_Of): Moved from Exp_Util. Ensure
	that the input has an entity.
