  Predicate is not called on an empty instance

  22.2.3.11 %TypedArray%.prototype.findIndex ( predicate [ , thisArg ] )

  %TypedArray%.prototype.findIndex is a distinct function that implements the
  same algorithm as Array.prototype.findIndex as defined in 22.1.3.9 except that
  the this object's [[ArrayLength]] internal slot is accessed in place of
  performing a [[Get]] of "length".

  ...

  22.1.3.9 Array.prototype.findIndex ( predicate[ , thisArg ] )

  ...
  6. Repeat, while k < len
    ...
    c. Let testResult be ToBoolean(? Call(predicate, T, « kValue, k, O »)).
  ...
  7. Return -1.
