5. Return ? AllocateArrayBuffer(NewTarget, byteLength).
24.1.1.1 AllocateArrayBuffer
3. Let block be ? CreateByteDataBlock(byteLength).
6.2.6.1 CreateByteDataBlock
1. Assert: sizeā„0.
2. Let db be a new Data Block value consisting of size bytes. If it is
impossible to create such a Data Block, throw a RangeError exception.
3. Set all of the bytes of db to 0.
4. Return db.
