commit r15-196-g98b26f695bdcb1e4eee2c27742fd6ab534bb7d55

    ada: Do not attempt to generate finalization actions with restricted profile
    
    These actions are not supported with this profile, but we were nevertheless
    attempting to generate them for protected objects.
    
    gcc/ada/
    
            * exp_ch7.adb (Build_Finalizer.Process_Declarations): Do not call
            Processing_Actions for simple protected objects if the profile is
            restricted.
            * exp_util.adb (Requires_Cleanup_Actions): Do not return True for
            simple protected objects if the profile is restricted.
