Support of parameter objects

When describing the properties of the object in the function is very convenient to use the syntax with multiple use of the @param tag, but I noticed that GCC though not throws warnings in this syntax, but does not support it fully

``` js
/**
* @param {{r: number}} params
*/
function foo(params) {

}

foo({r: 'd'}); // warning, all fine

/**
* @param {!Object} params
* @param {number} params.r
*/
function foo(params) {

}

foo({r: 'd'}); // fail, must be warning too
```
