	* exp_ch3.adb (Build_Record_Init_Proc/Freeze_Record_Type):
	Reimplementation of the support for abstract interface types in order
	to leave the code more clear and easy to maintain.

	* exp_ch6.adb (Freeze_Subprogram): Reimplementation of the support for
	abstract interface types in order to leave the code clearer and easier
	to maintain.

	* exp_disp.ads, exp_disp.adb (Fill_DT_Entry): Part of its functionality
	is now implemented by the new subprogram Fill_Secondary_DT_Entry.
	(Fill_Secondary_DT_Entry): Generate the code necessary to fill the
	appropriate entry of the secondary dispatch table.
	(Make_DT): Add code to inherit the secondary dispatch tables of
	the ancestors.

	* exp_util.adb (Find_Interface_Tag/Find_Interface_ADT): Instead of
	implementing both functionalities by means of a common routine, each
	routine has its own code.
