    Gets a concrete type for nn_modules. If share_types is True, the concrete
    type is fetched from concrete_type_store. If it is False, a new concrete type
    is created without first searching concrete_type_store.

    Args:
        nn_module:  The original Python nn.Module that we are creating a ScriptModule for.
        share_types = Whether to share underlying JIT types between modules (if possible).

    Returns:
        A concrete type for nn_module.

    Creates a new ScriptModule from an nn.Module

    Args:
        nn_module:  The original Python nn.Module that we are creating a ScriptModule for.
        stubs_fn:  Lambda that takes an nn.Module and generates a list of ScriptMethodStubs to compile.
        share_types:  Whether to share underlying JIT types between modules (if possible).
            NOTE: Only set to False this when we cannot guarantee type sharing will work
                correctly. This only happens today for traced modules, where the same
                module can produce different traced methods depending on the inputs.
        is_tracing: Whether this function is called during tracing or scripting. If tracing,
                we don't need to do AttributeTypeIsSupportedChecker because all the unsupported
                attributes will be baked as constant in the tracing graph. In addition,
                this check significantly slows down the traced modules when the module size is big.
