Nico Weber 8ebef785eb LibJS: Implement basic functionality of Array.from()
The optional 2nd and 3rd arguments are not yet implemented.

This assumes that `this` is the Array constructor and doesn't yet
implement the more general behavior in the ES6 spec that allows
transferring this method to other constructors.
