	* exp_ch3.ads (Build_Array_Invariant_Proc): moved to body.
	* exp_ch3.adb (Build_Array_Invariant_Proc,
	Build_Record_Invariant_Proc): transform into functions.
	(Insert_Component_Invariant_Checks): for composite types that have
	components with specified invariants, build a checking procedure,
	and make into the invariant procedure of the composite type,
	or incorporate it into the user- defined invariant procedure if
	one has been created.
	* sem_ch3.adb (Array_Type_Declaration): Checking for invariants
	on the component type is defered to the expander.

	* checks.adb (Apply_Parameter_Aliasing_And_Validity_Checks):
	Do not process subprogram renaminds because a) those cannot
	have PPC pragmas b) the renamed entity already has the PPCs.
	(Build_PPC_Pragma): Prepend a PPC pragma for consistency with
	Process_PPCs.
	* sem_ch6.adb (Last_Implicit_Declaration): Removed.
	(Process_PPCs): Insert a post condition body at the start of the
	declarative region of the related subprogram. This way the body
	will not freeze anything it shouldn't.
