// this function converts a shorthand object generator method into a normal
// (non-shorthand) object property which is a generator function expression. for
// example, this:
//
//  var foo = {
//    *bar(baz) { return 5; }
//  }
//
// should be replaced with:
//
//  var foo = {
//    bar: function*(baz) { return 5; }
//  }
//
// to do this, it clones the parameter array and the body of the object generator
// method into a new FunctionExpression.
//
// this method can be passed any Function AST node path, and it will return
// either:
//   a) the path that was passed in (iff the path did not need to be replaced) or
//   b) the path of the new FunctionExpression that was created as a replacement
//     (iff the path did need to be replaced)
//
// In either case, though, the caller can count on the fact that the return value
// is a Function AST node path.
//
// If this function is called with an AST node path that is not a Function (or with an
// argument that isn't an AST node path), it will throw an error.
