execution of the check that verifies that the partial view and

partial view, inherit properly its primitive operations.

(Access_Type_Declaration): Clean up declaration of malformed type
declared as an access to its own classwide type, to prevent cascaded

(Analyze_Package_Instantiation): Do not perform front-end inlining when
the current context is itself an instance within a non-instance child
unit, to prevent scope stack errors.
(Save_References): If the node is an aggregate that is an actual in a
call, rewrite as a qualified expression to preserve some type
information, to resolve possible ambiguities in the instance.
(Instance_Parent_Unit): New global variable to record the ultimate
parent unit associated with a generic child unit instance (associated
