	* repinfo.adb (List_Record_Info): During first loop,
	do not override the normalized position and first bit
	if they have already been set.	Move fallback code
	for the packed case to the case where it belongs.
	* sem_ch13.adb (Adjust_Record_For_Reverse_Bit_Order):
	Also adjust the normalized position of components.
	(Adjust_Record_For_Reverse_Bit_Order_Ada_95): Likewise.

	* exp_disp.adb (Make_DT, Set_All_DT_Position): Handle properly
	the placement of a primitive operation O that renames an operation
	R declared in an inner package, and which is thus not a primitive
	of the dispatching type of O. In this case O is a new primitive
	and does not inherit its dispatch table position from R (which
	has none).

	* sem_dim.adb (Analyze_Dimension_If_Expression,
	Analyze_Dimension_Case_Expression): new subprograms to verify
	the dimensional correctness of Ada2012 conditional expressions,
	and set properly the dimensions of the construct.
	* sem_res.adb (Resolve_If_Expression, Resolve_Case_Expression)):
	call Analyze_Dimension.
