* sem_cat.adb (Has_Stream_Attribute_Definition): If the type
has aspect specifications, examine the corresponding list of
representation items to determine whether there is a visible
stream operation. The attribute definition clause generated from
the aspect will be inserted at the freeze point of the type,
which may be in the private part and not directly visible,
but the aspect makes the operation available to a client.
