(Interface_Present_In_Ancestor): In case of concurrent types we can't
use the Corresponding_Record_Typ attribute to look for the interface
because it is set by the expander (and hence it is not always
available). For this reason we traverse the list of interfaces

* 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.

(Analyze_Return_Type): For the case of an anonymous access result type,

check if the entity also covers other abstract subprograms in the same

(New_Overloaded_Entity): For an overriding entity that comes from
source, note the operation that it overrides.
(Check_Conformance, Type_Conformant): Addition of one new formal
to skip controlling formals in the analysis. This is used to
handle overloading of abstract interfaces.
(Base_Types_Match): Add missing case for types imported from
