    Fix wrong assignment of aggregate to full-access component
    
    This is a regression present on the mainline: the compiler (front-end) fails
    to assign an aggregate to a full-access component (i.e. Atomic or VFA) as a
    whole if the type of the component is not full access itself.

            * freeze.adb (Is_Full_Access_Aggregate): Call Is_Full_Access_Object
            on the name of an N_Assignment_Statement to spot full access.
