Original issue's description:
> Amend DataView, ArrayBuffer, and TypedArray methods to use ToIndex.
>
> The spec was modified to relax some requirements which implementors had not been
> enforcing. Part of this process involved introducing a new abstract operation
> ToIndex, which had partial overlap with our existing semantics as well as some
> differences (most notably treating undefined as 0). Test262 tests were introduced to
> check for the new semantics, some of which we were failing. This patch amends the
> parts of our implementation corresponding to specification algorithms which use
> ToIndex to follow its semantics precisely.
