Using Types from Modules in Non-global Scopes

Currently, the following type references work well due to the InlineAlias pass:

``` js
const Foo = require('./foo');

/** @param {Foo} */
function bar(foo) {}
```

However, as soon as the code is no longer in a global scope (like an IIFE), then the pass doesn't function and the type cannot be resolved.

``` js
(function() {
const Foo = require('./foo');

/** @param {Foo} */
function bar(foo) {}
})()
```

This easily occurs with the changes in #1630.

The current work around is to use module path references:

``` js
(function() {
const Foo = require('./foo');

/** @param {./foo} */
function bar(foo) {}
})()
```

I think it's overly restrictive for this to only function in the global scope. It makes the functionality very brittle and hard to explain to users.
