<h3>Log Message</h3>
<pre>IntlObject should not be using JSArray::initializeIndex().
https://bugs.webkit.org/show_bug.cgi?id=170302
<rdar://problem/31356918>
Reviewed by Saam Barati.
JSArray::initializeIndex() is only meant to be used with arrays created using
JSArray::tryCreateForInitializationPrivate() under very constrained conditions.
