	* exp_ch5.adb, layout.adb, einfo.adb, einfo.ads, sem_prag.adb,
	freeze.adb, freeze.ads, sem_util.adb, sem_util.ads, exp_ch2.adb,
	exp_ch4.adb, errout.adb, exp_aggr.adb, sem_ch13.adb: This is a general
	change that deals with the fact that most of the special coding for
	Atomic should also apply to the case of Volatile_Full_Access.
	A new attribute Is_Atomic_Or_VFA is introduced, and many of the
	references to Is_Atomic now use this new attribute.
