	* sem_prag.ads, sem_prag.adb (Build_Classwide_Expression): Include
	overridden operation as parameter, in order to map formals of
	the overridden and overring operation properly prior to rewriting
	the inherited condition.
	* freeze.adb (Check_Inherited_Cnonditions): Change call to
	Build_Class_Wide_Expression accordingly.  In Spark_Mode, add
	call to analyze the contract of the parent operation, prior to
	mapping formals between operations.

	* adabkend.adb (Scan_Back_End_Switches): Ignore -o/-G switches
	as done in back_end.adb.
	(Scan_Compiler_Args): Remove special case for CodePeer/SPARK, no longer
	needed, and prevents proper handling of multi-unit sources.
