	from table Add Last field to record last entry used.

	* a-cdlili.adb, a-cdlili.ads, a-cohama.adb, a-cohama.ads,
	* a-cohase.adb, a-cohase.ads, a-convec.adb, a-convec.ads,
	* a-coorma.adb, a-coorma.ads, a-coorse.adb, a-coorse.ads:
	(Pseudo_Reference, Element_Access, Get_Element_Access): New
	declarations added for use by performance improvements in exp_ch5.adb.
	* snames.ads-tmpl: New names referenced by exp_ch5.adb.
	* exp_ch5.adb: Speed up "for ... of" loops for predefined containers.
	Instead of doing literally what the RM calls for, we do something
	equivalent that avoids expensive operations inside the loop. If the
	container package has appropriate Next, Pseudo_Reference,
	Element_Access, Get_Element_Access declarations, we invoke the
	optimization.
	* snames.ads-tmpl: Note speed improvement.
