 Constant folding is performed as part of shape inference, unless disabled (from the CLI pass `--no-fold-constants` to disable). This
 is done in order to support models that dynamically calculate shapes using operators such as `Shape`/`Squeeze`/`Unsqueeze` depending
 on dynamically set dimension parameters (e.g. batch size).
