ToIndex conversions on byteOffset

1. Let v be the this value.
2. If littleEndian is not present, let littleEndian be false.
3. Return ? SetViewValue(v, byteOffset, littleEndian, "Float64", value).
24.2.1.2 SetViewValue ( view, requestIndex, isLittleEndian, type, value )
...
4. Let getIndex be ? ToIndex(requestIndex).
