  Set values on the little endian order
info: |
  24.2.4.17 DataView.prototype.setInt32 ( byteOffset, value [ , littleEndian ] )

  1. Let v be the this value.
  2. If littleEndian is not present, let littleEndian be false.
  3. Return ? SetViewValue(v, byteOffset, littleEndian, "Int32", value).

  24.2.1.2 SetViewValue ( view, requestIndex, isLittleEndian, type, value )

  ...
  15. Let bufferIndex be getIndex + viewOffset.
  16. Return SetValueInBuffer(buffer, bufferIndex, type, numberValue, isLittleEndian).

  24.1.1.6 SetValueInBuffer ( arrayBuffer, byteIndex, type, value [ , isLittleEndian ] )

  ...
  11. Store the individual bytes of rawBytes into block, in order, starting at
  block[byteIndex].
  12. Return NormalCompletion(undefined).
