Add option to disable string array literal peephole optimization

This was initially posted [to mailing list](https://groups.google.com/forum/#!topic/closure-compiler-discuss/NAJEIwckYeE), but no one replied, so here is the feature request.

I have AMD module with following line:

```javascript
define(['@detox/crypto', '@detox/dht', '@detox/utils', 'ronion', 'fixed-size-multiplexer', 'async-eventer', 'pako'], Wrapper)
```

The issue is that starting with 6th depedency Closure Compiler in advanced mode decides that it is a good idea to replace that array with splitted string like this:

```javascript
define("@detox/crypto @detox/dht @detox/utils ronion fixed-size-multiplexer async-eventer pako".split(" "),A)
```

Which makes sense in general, but fails when I try to use minified result with https://github.com/requirejs/r.js, which doesn't understand such construction and requires explicit array of dependencies.

It would be very useful to have an option to disable this particular optimization in advanced mode.
