+ Returns given initialValue on empty instances without calling callbackfn
+info: |
+ 22.2.3.20 %TypedArray%.prototype.reduce ( callbackfn [ , initialValue ] )
+
+ %TypedArray%.prototype.reduce is a distinct function that implements the same
+ algorithm as Array.prototype.reduce as defined in 22.1.3.19 except that the
+ this object's [[ArrayLength]] internal slot is accessed in place of performing
+ a [[Get]] of "length".
+
+ 22.1.3.19 Array.prototype.reduce ( callbackfn [ , initialValue ] )
+
+ ...
+ 7. Else initialValue is not present,
+ ...
+ b. Repeat, while kPresent is false and k < len
+ ...
+ iii. If kPresent is true, then
+ 1. Let accumulator be ? Get(O, Pk).
+ iv. Increase k by 1.
+ ...
+ 8. Repeat, while k < len
+ ...
+ 9. Return accumulator.
