[COMMITTED] ada: Remove dead code in Expand_Iterator_Loop_Over_Container

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

From: Eric Botcazou <ebotcazou@adacore.com>

The Condition_Actions field can only be populated for while loops.

gcc/ada/

	* exp_ch5.adb (Expand_Iterator_Loop_Over_Container): Do not insert
	an always empty list. Remove unused parameter Isc.
	(Expand_Iterator_Loop): Adjust call to above procedure.

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