Empty record type is not supported

Empty record type is not supported.

```js
/**
* @type {{}} // WARNING - [JSC_TYPE_PARSE_ERROR] Bad type annotation. type not recognized due to syntax error.
*/
const x = {}
```

I think it could be useful to have an empty record type. It comes in handy for example when dealing with React components.
