ada: Plug small loophole in finalization machinery

The path in Expand_N_If_Expression implementing the special optimization for
an unidimensional array type and dependent expressions with static bounds
fails to call Process_Transients_In_Expression on their list of actions.

gcc/ada/

	* exp_ch4.adb (Expand_N_If_Expression): Also add missing calls to
	Process_Transients_In_Expression on the code path implementing the
	special optimization for an unidimensional array type and
	dependent expressions with static bounds.
