	* exp_util.adb (Add_Own_DIC): Ensure that the expression of the pragma
	is available (Is_Verifiable_DIC_Pragma): Moved from Sem_Util.
	* sem_util.adb (Has_Full_Default_Initialization):
	Has_Fully_Default_Initializing_DIC_Pragma is now used to determine
	whether a type has full default initialization due to pragma
	Default_Initial_Condition.
	(Has_Fully_Default_Initializing_DIC_Pragma): New routine.
	(Is_Verifiable_DIC_Pragma): Moved to Exp_Util.
	* sem_util.ads (Has_Fully_Default_Initializing_DIC_Pragma): New
	routine.
	(Is_Verifiable_DIC_Pragma): Moved to Exp_Util.

	* exp_aggr.adb (In_Place_Assign_OK): Extend the predicate to recognize
	an array aggregate in an allocator, when the designated type is
	unconstrained and the upper bound of the aggregate belongs to the base
	type of the index.

	* exp_ch6.adb (Expand_N_Extended_Return_Statement,
	Expand_Simple_Function_Return): Assert that the b-i-p-ness of the
	caller and callee match.  Otherwise, we would need some substantial
	changes to allow b-i-p calls non-b-i-p, and vice versa.
