    Performs a set of optimization passes to optimize a model for the
    purposes of inference. Specifically, the passes that are run are:
    1. Conv/BN fusion
    2. Dropout removal
    3. MKL layout optimizations

    The third optimization takes a function `use_mkl_heuristic` that's used
    to determine whether a subgraph should be explicitly run in MKL layout.

    Note: As FX does not currently handle aliasing, this pass currently
    assumes nothing aliases. If that isn't true, use at your own risk.
