    [Ada] Fix incorrect call to inherited function with limited return type
    
    This is a return convention mismatch coming from a discrepancy of the
    Returns_By_Ref flag for the inherited function.

            * sem_ch3.adb (Derive_Subprogram): For a function, also copy the
            Returns_By_Ref flag from the parent.
