	* sem_ch4.adb (Remove_Abstract_Interpretations): Even if there are no
	abstract interpretations on an operator, remove interpretations that
	yield Address or a type derived from it, if one of the operands is an
	integer literal.
	(Try_Object_Operation.Try_Primitive_Operation,
	Try_Object_Operation.Try_Class_Wide_Operation): Set proper source
	location when creating the new reference to a primitive or class-wide
	operation as a part of rewriting a subprogram call.
	(Try_Primitive_Operations): If context requires a function, collect all
	interpretations after the first match, because there may be primitive
	operations of the same type with the same profile and different return
	types. From code reading.
	(Try_Primitive_Operation): Use the node kind to choose the proper
	operation when a function and a procedure have the same parameter
	profile.
	(Complete_Object_Operation): If formal is an access parameter and prefix
	is an object, rewrite as an Access reference, to match signature of
	primitive operation.
	(Find_Equality_Type, Find_One_Interp): Handle properly equality given
	by an expanded name with prefix Standard, when the operands are of an
	anonymous access type.
	(Remove_Abstract_Operations): If the operation is abstract because it is
	inherited by a user-defined type derived from Address, remove it as
	well from the set of candidate interpretations of an overloaded node.
	(Analyze_Membership_Op): Membership test not applicable to cpp-class
	types.
