	* sem_attr.adb (Resolve_Attribute, case 'Address): For an illegal
	'Address attribute reference with an overloaded prefix, use the
	location of the prefix (not the location of the attribute reference) as
	the error location.
	(Analyze_Attribute, case 'Size): The name of an enumeration literal, or
	a function renaming thereof, is a valid prefix for 'Size (where it is
	intepreted as a function call).
	(Statically_Denotes_Entity): New predicate to determine whether the
	prefix of an array attribute can be considered static.

	PR ada/9087
	(Eval_Attr): Fix failure to evaluate Component_Size for
	unconstrained arrays (resulted in wrong value in packed case, since
	back end cannot handle this case)
