* sem_res.adb (Resolve_Type_Conversion): In case of conversion to an
abstract interface type, the static analysis is not enough to know if
the interface is implemented or not by the source tagged type. Hence
we must pass the work to the expander to generate the required code to
evaluate the conversion at run-time.
(Resolve_Equality_Op): Do not apply previous
transformation if expansion is disasbled, to prevent anomalies when
locating global references in a generic unit.

* sem_ch6.adb (Build_Body_To_Inline): Enforce the rule that in order

* sem_ch3.adb (Build_Discriminated_Subtype): In case of concurrent

Corresponding_Record_Type (which has the list of primitive operations).
(Check_Anonymous_Access_Types): When creating anonymous access types for
access components, use Rewrite in order to preserve the tree structure,
for ASIS use.
(Analyze_Object_Declaration): For limited types with access
discriminants with defaults initialized by an aggregate, obtain
subtype from aggregate as for other mutable types.
(Derived_Type_Declaration): If the derived type is a limited interface,
set the corresponding flag (Is_Limited_Record is not sufficient).
