	* sem_ch13.adb (Add_Predicates): if the type is declared in
	an inner package it may be frozen outside of the package, and
	the generated pragma has not been analyzed yet, the expression
	for the predicate must be captured and added to the predicate
	function at this point.

	* contracts.adb (Analyze_Package_Body_Contract): Do not check
	for a missing package refinement because 1) packages do not have
	"refinement" and 2) the check for proper state refinement is
	performed in a different place.
	* einfo.adb (Has_Non_Null_Visible_Refinement): Reimplemented.
	(Has_Null_Visible_Refinement): Reimplemented.
	* sem_ch3.adb (Analyze_Declarations): Determine whether all
	abstract states have received a refinement and if not, emit
	errors.

	cleanup. Determine whether all abstract states of the
	package and any nested packages have received a refinement
	and if not, emit errors.
	(Requires_Completion_In_Body): Add new formal parameter
	Do_Abstract_States. Update the comment on usage. Propagate the
	Do_Abstract_States flag to all Unit_Requires_Body calls.
	(Unit_Requires_Body): Remove formal
	parameter Ignore_Abstract_States. Add new formal paramter
	Do_Abstract_States. Propagate the Do_Abstract_States flag to
	all Requires_Completion_In calls.
	* sem_ch7.ads (Unit_Requires_Body): Remove formal
	parameter Ignore_Abstract_States. Add new formal paramter
	Do_Abstract_States. Update the comment on usage.
	* sem_ch9.adb (Analyze_Single_Protected_Declaration): Do
	not initialize the constituent list as this is now done on a
	need-to-add-element basis.
	(Analyze_Single_Task_Declaration):
	Do not initialize the constituent list as this is now done on
	a need-to-add-element basis.
	* sem_ch10.adb (Decorate_State): Do not initialize the constituent
	lists as this is now done on a need-to-add-element basis.
	* sem_prag.adb (Analyze_Constituent): Set the
	refinement constituents when adding a new element.
	(Analyze_Part_Of_In_Decl_Part): Set the Part_Of constituents when
	adding a new element.
	(Analyze_Part_Of_Option): Set the Part_Of
	constituents when adding a new element.
	(Analyze_Pragma): Set the Part_Of constituents when adding a new
	element.
	(Check_Constituent_Usage (all versions)): Reimplemented.
	(Collect_Constituent): Set the refinement constituents when adding
	a new element.
	(Create_Abstract_State): Do not initialize the
	constituent lists as this is now done on a need-to-add-element basis.
	(Propagate_Part_Of): Set the Part_Of constituents when
	adding a new element.
	* sem_util.adb (Check_State_Refinements): New routine.
	(Has_Non_Null_Refinement): Reimplemented.
