    Original change's description:
    > [turboprop] Add a slot for optimization marker in feedback vector
    >
    > Optimization marker and the optimized code used to share the same slot
    > in the feedback vector as they were mutually exclusive. With turboprop
    > we would want to mark the function for tier up to Turbofan while holding
    > the optimized code for Turboprop. So this cl uses the existing padding
    > field to hold the optimization marker instead.
    >
    > As a driveby, removes unused JSFunction::ClearOptimizedCodeSlot function
    > and fixes a minor bug in Runtime_GetOptimizationStatus.
