Return abrupt from firstElement's toLocaleString => valueOf

22.2.3.28 %TypedArray%.prototype.toLocaleString ([ reserved1 [ , reserved2 ] ])
%TypedArray%.prototype.toLocaleString is a distinct function that implements
the same algorithm as Array.prototype.toLocaleString as defined in 22.1.3.27
except that the this object's [[ArrayLength]] internal slot is accessed in
place of performing a [[Get]] of "length".
22.1.3.27 Array.prototype.toLocaleString ( [ reserved1 [ , reserved2 ] ] )
...
5. Let firstElement be ? Get(array, "0").
6. If firstElement is undefined or null, then
a. Let R be the empty String.
7. Else,
a. Let R be ? ToString(? Invoke(firstElement, "toLocaleString")).
8. Let k be 1.
9.Repeat, while k < len
a. Let S be a String value produced by concatenating R and separator.
b. Let nextElement be ? Get(array, ! ToString(k)).
c. If nextElement is undefined or null, then
i. Let R be the empty String.
d. Else,
i. Let R be ? ToString(? Invoke(nextElement, "toLocaleString")).
