<h3>Log Message</h3>
<pre>Merge <a href="http://trac.webkit.org/projects/webkit/changeset/196847">r196847</a> - bmalloc: Chunk, Page, and Line don't need to be class templates
https://bugs.webkit.org/show_bug.cgi?id=154480

We needed class templates to distinguish between small and medium,
but medium is gone now.
