ada: Crash checking accessibility level on private type

This patch fixes an issue in the compiler whereby calculating a static
accessibility level on a private type with an access discriminant resulted
in a compile time crash when No_Dynamic_Accessibility_Checks is enabled.

	* accessibility.adb (Accessibility_Level): Use Get_Full_View to
	avoid crashes when calculating scope.
