  %TypedArray%.prototype.lastIndexOf ( searchElement [ , fromIndex ] )

  %TypedArray%.prototype.lastIndexOf is a distinct function that implements
  the same algorithm as Array.prototype.lastIndexOf as defined in 22.1.3.17
  except that the this value's [[ArrayLength]] internal slot is accessed
  in place of performing a [[Get]] of "length".

  Array.prototype.lastIndexOf ( searchElement [ , fromIndex ] )

  [...]
  8. Return -1.
