	expression to insert an elab check using a conditional expression, be
	sure to carry the original list of interpretations to the new location.

	* sem_type.ads, sem_type.adb (In_Generic_Actual): Leave this subprogram
	at the library level and fix a hidden bug in its implementation: its
	functionality for renaming objects was broken because
	N_Object_Renaming_Declarations nodes are not a subclass of
	N_Declaration nodes (as documented in sinfo.ads).
	* sem_util.adb (Check_Dynamically_Tagged_Expression): Include in this
	check nodes that are actuals of generic instantiations.

	* sinfo.ads, sinfo.adb (Pending_Context): New flag to indicate that the
	context of a compilation unit is being analyzed. Used to detect
	circularities created by with_clauses that are not detected by the
	loading machinery.
	* sem_ch10.adb (Analyze_Compilation_Unit): Set Pending_Context before
	analyzing the context of the current compilation unit, to detect
	possible circularities created by with_clauses.
