exp_util.adb (Remove_Side_Effects): Properly propagate arguments to recursive calls.

2005-03-29  Robert Dewar  <dewar@adacore.com>

	* exp_util.adb (Remove_Side_Effects): Properly propagate arguments to
	recursive calls.
	(Is_Possibly_Unaligned_Object): Correct typo that
	resulted in inaccurate result for unaligned scalars within records.
