+	Base_Type_Only. The problem is that the base type of a type is
+	indeed a base type when Set_Base_Type is called, but then the
+	type is mutated into a subtype in rare cases.
+	* atree.ads, atree.adb (Is_Entity): Export. Correct subtype of
+	parameter in body.
+	* gen_il-gen.adb: Improve getters so that "Pre => ..." can refer
+	to the value of the field. Put Warnings (Off) on some with

+	Pre's.

+

+	the ordering of Mutate_Kind and Set_Directly_Designated_Type;
+	remove temporary setting of Ekind to E_Access_Type for building
+	_master objects, since now the Ekind is already set to its final
+	value. Move repeated code into Setup_Access_Type routine and use
+	it so that Process_Subtype is executed before mutating the kind
+	of the type entity.
+	* gen_il-gen-gen_entities.adb (Gen_Entities): Remove
+	Directly_Designated_Type from E_Void, E_Private_Record,
+	E_Limited_Private_Type and Incomplete_Kind; now it only belongs
+	to Access_Kind entities.
+	* sem_util.adb: Minor reformatting.
