    Mark the IntVars that are not present in any input's shape

    be able to distinguish these dynamic dims in the codegen

    relying on / validating the pre-set value. To this end,

    code generation of the ops.

    the total_length dimension of the resulting jagged Tensor
    if it hasn't been set from any of the model input's shape.
    Another example is the make_jagged op that should set the
    batch_dim within the JaggedIntVar of the resulting jagged
    Tensor, unless it has been set already from the inputs.
