Jakob Kummerow 6c07d6e3d8 [typedarray] Throw rather than crash when too large to sort
Sorting a TypedArray with a custom compare function requires us to
copy the array's contents to a FixedArray. When the TypedArray is
larger than FixedArray::kMaxLength, we should throw a RangeError
rather than crashing with an OOM message.
