	* sem_res.adb (Resolve_Membership_Op): In case of the membership test
	"Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
	the expander will generate the corresponding run-time check to evaluate
	the expression.
	(Resolve_Call): Check for legal type of procedure name or prefix that
	appears as a trigger in a triggering alternative.
	(Valid_Conversion): If expression is ambiguous and the context involves
	an extension of System, remove System.Address interpretations.
	(Resolve_Qualified_Expression): Reject the case of a specific-type
	qualification applied to a class-wide argument. Enhance comment
	to explain checking of Original_Node.
	(Resolve_Type_Conversion): The location of the error message was not
	general enough to handle the general case and hence it has been removed.
	In addition, this patch improves the text of the message.
	(Resolve_Type_Conversion): Add missing support for access to interface
	types.
	(Resolve_Type_Conversion): If the target is a class-wide interface type,
	do not expand if the expression is the actual in a call, because proper
	expansion will take place when the call itself is expanded.
	(Resolve_Allocator): If the context is an unchecked conversion, the
	allocator inherits its storage pool, if any, from the target type of
	the conversion.
