	* exp_ch6.adb (Add_Or_Save_Precondition): New routine.
	(Collect_Body_Postconditions_In_Decls): New routine.
	(Collect_Body_Postconditions_Of_Kind): Factor out code. Handle
	postcondition aspects or pragmas that appear on a subprogram
	body stub.
	(Collect_Spec_Preconditions): Factor out code. Handle
	precondition aspects or pragmas that appear on a subprogram
	body stub.
	* sem_ch6.adb (Analyze_Subprogram_Body_Helper): The analysis of
	aspects that apply to a subprogram body stub is no longer delayed,
	the aspects are analyzed on the spot.
	(SPARK_Aspect_Error):
	Aspects that apply to a subprogram declaration cannot appear in
	a subunit.
	* sem_ch10.adb Remove with and use clause for Sem_Ch13.
	(Analyze_Proper_Body): Add local variable Comp_Unit. Unum
	is now a local variable. Code cleanup. Analysis related to
	the aspects of a subprogram body stub is now carried out by
	Analyze_Subprogram_Body_Helper. Do not propagate the aspects
	and/or pragmas of a subprogram body stub to the proper body
	as this is no longer needed. Do not analyze the aspects of a
	subprogram stub when the corresponding source unit is missing.
	(Analyze_Protected_Body_Stub): Flag the illegal use of aspects
	on a stub.
	(Analyze_Task_Body_Stub): Flag the illegal use of
	aspects on a stub.
	(Optional_Subunit): Add local variable Unum.
	* sem_ch13.adb (Insert_Delayed_Pragma): Do not analyze a generated
	pragma when it applies to a subprogram body stub.
	* sem_prag.adb (Analyze_Pragma): Pragmas Contract_Cases,
	Depends and Global can now apply to a subprogram body stub as
	long as it acts as its own spec.
	(Analyze_Refined_Pragma):
	Code reformatting. Refinement pragmas cannot apply to a subunit.

	* einfo.ads Update the usage of flag
	Uses_Sec_Stack. Uses_Sec_Stack now applies to E_Loop entities.
	* exp_ch5.adb (Expand_Iterator_Loop): The temporary for a cursor
	now starts with the letter 'C'. This makes reading expanded
	code easier.
	* exp_ch7.adb (Establish_Transient_Scope): Add local variable
	Iter_Loop. Signal that an Ada 2012 iterator loop requires
	secondary stack management when creating a transient scope for
	an element reference.
	* exp_util.adb (Process_Statements_For_Controlled_Objects):
	When wrapping the statements of a loop, pass the E_Loop entity
	to the wrapping machinery.
	(Wrap_Statements_In_Block): Add
	formal parameter Scop along with comment on usage. Add local
	variables Block_Id, Block_Nod and Iter_Loop. Mark the generated
	block as requiring secondary stack management when the block is
	created inside an Ada 2012 iterator loop. This ensures that any
	reference objects are reclaimed on each iteration of the loop.
	* sem_ch5.adb (Analyze_Loop_Statement): Mark the generated block
	tasked with the handling of container iterators as requiring
	secondary stack management. This ensures that iterators are
	reclaimed when the loop terminates or is exited in any fashion.
	* sem_util.adb (Add_Block_Identifier): New routine.
	(Find_Enclosing_Iterator_Loop): New routine.
	* sem_util.ads (Add_Block_Identifier): New routine.
	(Find_Enclosing_Iterator_Loop): New routine.
