New issue 4128 by [email protected]: TypedArray methods should use
InternalArray, not Array, as an accumulator
https://code.google.com/p/v8/issues/detail?id=4128
This comes up in cases like TypedArray.from, TypedArray.filter, etc, where
there is a pattern of creating an array and then manipulating it.
InternalArray, rather than global.Array, is not customizable by the user.
arv@ points out that this is observable:
```
I think we have an issue with typed arrays since we are creating a new Array
which can have setters.
Object.defineProperty(Array.prototype, 1, {set: function(v) {
alert(v);
});
For the typed arrays we can use InternalArray (where the spec asks for a
List).
```
