DataView.prototype.getBigInt64 ( byteOffset [ , littleEndian ] )
1. Let v be the this value.
2. If littleEndian is not present, let littleEndian be undefined.
3. Return ? GetViewValue(v, byteOffset, littleEndian, "Int64").
24.3.1.1 GetViewValue ( view, requestIndex, isLittleEndian, type )
...
4. Let getIndex be ? ToIndex(requestIndex).
