	* freeze.adb (Freeze_Expression): Rename local variable Cspc to Spec

	* einfo.adb (Set_Invariant_Procedure, Set_Predicate_Function):
	chain properly subprograms on Subprograms_For_Type list.
	* sem_ch13.ads; (Build_Invariant_Procedure_Declaration): new
	procedure, to create declaration for invariant procedure
	independently of the construction of the body, so that it can
	be called within expression functions.
	* sem_ch13.adb (Build_Invariant_Procedure): code cleanup. The
	declaration may already have been generated at the point an
	explicit invariant aspect is encountered.
	* sem_prag.adb; (Analyze_Pragma, case Invariant): create declaration
	for invariant procedure.
	* sem_ch7.adb (Analyze_Package_Specification): clean up call to
	build invariant procedure.
	(Preserve_Full_Attributes): propagate information about invariants
	if they appear on a completion,
