Original change's description:
> [dart2wasm] Use DataView in JS typed arrays
>
> Refcator JS typed array classes to store JS `DataView`s (instead of JS
> typed array with the matching type), and use V8's new optimized
> `DataView` imports.
>
> Brings JS typed array class performance from unusable to reasonable
> levels. In `SkeletalAnimation` benchmark:
>
> - Before: 1444 us.
> - After: 101 us.
>
> Future work:
>
> - Make immutable classes extend the mutable ones. This will allow `[]`
> calls to be always inlined in JSCM.
>
> - Move list mixin applications from the base class to implementation
> classes. This will allow members like `elementAt`, `forEach` etc. to
> have direct calls to other methods of the same class.
>
> - Try adding a `length` field to avoid JS calls in bounds checks.
