Throws a RangeError if getIndex + elementSize > viewSize
info: |
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 )
...
10. Let viewOffset be the value of view's [[ByteOffset]] internal slot.
11. Let viewSize be the value of view's [[ByteLength]] internal slot.
12. Let elementSize be the Number value of the Element Size value specified in
Table 50 for Element Type type.
13. If getIndex + elementSize > viewSize, throw a RangeError exception.
