[COMMITTED] ada: Further cleanup in finalization machinery

["Marc Poulhiès" <poulhies@adacore.com>]

From: Eric Botcazou <ebotcazou@adacore.com>

This removes the specific treatment of transient scopes in initialization
procedures, which is obsolete.

gcc/ada/

	* exp_aggr.adb (Convert_To_Assignments): Do not treat initialization
	procedures specially when it comes to creating a transient scope.
	* exp_ch7.adb (Build_Finalizer.Process_Declarations): Likewise.
	* exp_util.adb (Requires_Cleanup_Actions): Likewise.

Tested on x86_64-pc-linux-gnu, committed on master.
