[Ada] Get rid of more references to Universal_Integer in expanded code

2020-06-03  Eric Botcazou  <ebotcazou@adacore.com>

gcc/ada/

	* libgnat/s-atopar.adb (Atomic_Fetch_And_Add): Make use of an
	equivalent static expression.
	(Atomic_Fetch_And_Subtract): Likewise.
	(Is_Lock_Free): Likewise.
	* libgnat/s-atopex.adb (Atomic_Exchange): Likewise.
	(Atomic_Compare_And_Exchange): Likewise.
	(Is_Lock_Free): Likewise.
