They are added under the global scope object, as follows:

  {
    "memory": ...,
    "globals": {
      "global#0": ...,
      "global#1": ...,
      "global#2": ...,
    }
  }

We currently don't have any way to name globals in the wasm binary
format, but it is possible to extend the name section with these names
in the future.
