Subject: [PATCH] Normative: Make SharedArrayBuffer's sole parameter required
 (#2393)

SharedArrayBuffer.length is 1 on all web engines (as is
ArrayBuffer.length). Unsure why this was made optional.

eshost output for `print(SharedArrayBuffer.length)`:

```
1

1

1

1
```

           1. If NewTarget is *undefined*, throw a *TypeError* exception.
