  22.2.3.17 %TypedArray%.prototype.lastIndexOf ( searchElement [ , fromIndex ] )

  %TypedArray%.prototype.lastIndexOf is a distinct function that implements the
  same algorithm as Array.prototype.lastIndexOf as defined in 22.1.3.15 except
  that the this object's [[ArrayLength]] internal slot is accessed in place of
  performing a [[Get]] of "length".

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

  ...
  4. If argument fromIndex was passed, let n be ? ToInteger(fromIndex); else let
  n be len-1.
