	* einfo.ads, einfo.adb (First_Tag_Component): Protect the frontend

	corresponding full type declaration is missing and pragma CPP_Virtual
	is used.

	(Has_Pragma_Pure): New flag

	explicitly declared limited.
	(DT_Offset_To_Top_Func): New attribute that is present in E_Component
	entities. Only used for component marked Is_Tag. If present it stores
	the Offset_To_Top function used to provide this value in tagged types
	whose ancestor has discriminants.

	* sem_ch7.adb: Maintain status of new Is_Known_Null flag

	read the version string from the tree even if its length is not the
	same as the length of the version string computed from Gnatvsn.

	Define Tree_Version_String as a dynamic string.
