<p>This function does the q7 to q15 expansion with re-ordering</p>
<pre>
| A1 | A2 | A3 | A4 |</pre><pre> 0 7 8 15 16 23 24 31
</pre><p>is converted into:</p>
<pre>
| A1 | A3 | and | A2 | A4 |</pre><pre> 0 15 16 31 0 15 16 31
</pre><p>This looks strange but is natural considering how sign-extension is done at assembly level.</p>
<p>The expansion of other other oprand will follow the same rule so that the end results are the same.</p>
<p>The tail (i.e., last (N % 4) elements) will still be in original order. </p>
