[Ada] Reuse collective subtype for comparison operators where possible

Replace membership alternatives with N_Op_Compare. Code cleanup;
semantics is unaffected.

gcc/ada/

	* sem_res.adb (Resolve_Actuals): Simplify with N_Op_Compare.
	* sem_util.adb (Replace_Null_Operand,
	Null_To_Null_Address_Convert_OK): Likewise.
