  Add support for arrays of arrays to VariableLocation
  
  Array indices are sorted so that the outermost index is in the back.
  This is because we want to be consistent with future arrays of arrays
  parsing code. In parsing we'll have a utility function to make a
  TType object into an array, and there it's most natural to push the
  new outermost sizes to the back of the vector.
  
  Further patches will still be needed to parse arrays of arrays and
  add support to arrays of arrays into the API.
