Make the transition to ArrayBuffer backed Arrays (#70)

* Traverse base classes when resolving overloads
* Implement preliminary TypedArray accessors
* Extract decorator flags from common flags to make space
* Add '**' overload
* Implement basic explicit inlining
* Support inlining of instance methods
* Reduce number of required locals when inlining
* Implement inlining of operator overloads
* Fix issues when inlining generic functions
