	Analyze_Quantified_Expression, Analyze_Slice,
	Analyze_Null): issue an error in formal mode on unsupported constructs
	* sem_ch5.adb
	(Analyze_Block_Statement): only issue error on source block statement
	* sem_util.ads, sem_util.adb (Last_Source_Node_In_Sequence): new

	Last_Source_Node_In_Sequence
	* sem_ch8.adb (Analyze_Exception_Renaming, Analyze_Generic_Renaming,
	Analyze_Object_Renaming, Analyze_Use_Package): issue an error in formal
	mode on unsupported constructs
	* sem_ch9.adb Do not return after issuing error in formal mode, as the

	not serious.
