	expressions are valid names.

	* sem_ch10.adb (Analyze_Compilation_Unit): If the unit is an
	instantiation do not emit warnings for obsolescent units. The
	warnings belong on the corresponding generic.

	* einfo.adb: Update the usage of Node15.
	(Return_Flag_Or_Transient_Decl): Removed.
	(Set_Return_Flag_Or_Transient_Decl): Removed.
	(Set_Status_Flag_Or_Transient_Decl): New routine.
	(Status_Flag_Or_Transient_Decl): New routine.
	(Write_Field15_Name): Update the output for variables and constants.
	* einfo.ads: Remove attribute
	Return_Flag_Or_Transient_Decl along with occurrences in nodes.
	(Return_Flag_Or_Transient_Decl): Removed along with pragma Inline.
	(Set_Return_Flag_Or_Transient_Decl): Removed along with pragma Inline.
	(Set_Status_Flag_Or_Transient_Decl): New routine along with pragma
	Inline.
	(Status_Flag_Or_Transient_Decl): New routine along with pragma Inline.
	* exp_ch4.adb (Create_Alternative): New routine.
	(Expand_N_Conditional_Expression): Handle the case
	where at least one of the conditional expression
	alternatives prodices a controlled temporary by means of a function
	call.
	(Is_Controlled_Function_Call): New routine.
	(Process_Transient_Object): Update the call to
	Set_Return_Flag_Or_Transient_Decl.
	* exp_ch6.adb (Enclosing_Context): New routine.
	(Expand_N_Extended_Return_Statement): Update all calls to
	Set_Return_Flag_Or_Transient_Decl.
	(Expand_Ctrl_Function_Call): Prohibit the finalization of a controlled
	function result when the context is a conditional expression.
	* exp_ch7.adb (Process_Declarations): Update all calls to
	Return_Flag_Or_Transient_Decl. Add processing for intermediate
	results of conditional expressions where one of the alternatives
	uses a controlled function call.
	(Process_Object_Declaration): Update all calls to
	Return_Flag_Or_Transient_Decl and rearrange the logic to process
	"hook" objects first.
	(Process_Transient_Objects): Update the call to
	Set_Return_Flag_Or_Transient_Decl.
	* exp_util.adb (Requires_Cleanup_Actions (List_Id, Boolean,
	Boolean)): Update all calls to Return_Flag_Or_Transient_Decl. Add
	detection for intermediate results of conditional expressions
	where one of the alternatives uses a controlled function call.
