	as a prefixed call with local references.
	* sem_ch3.adb (Is_Visible_Component): In an instance body a selected
	component is always visible.
	* sem_ch4.adb (Analyze_Selected_Component): If the node is a
	prefixed call in an instance, do not look for visible components
	of the type.
	* sem_ch12.adb (Reset_Entity): If a selected component has resolved
	to a prefixed call, mark the node accordingly when prefix and
	selector are local references.

	* gnatvsn.ads (Current_Year): Bump to 2012.
