<pre>RenderInline::clone() should return RenderPtr.

&lt;https://webkit.org/b/126514&gt;

Patch by Gurpreet Kaur &lt;k.gurpreet@samsung.com&gt; on 2014-01-06

Reviewed by Antti Koivisto.

* rendering/RenderInline.h:

* rendering/RenderInline.cpp:

(WebCore::RenderInline::clone):

    Tweaked to return RenderPtr&lt;RenderInline&gt;.

(WebCore::RenderInline::splitInlines):

    Store cloned RenderInlines in RenderPtrs. Use leakPtr() to sink

    them into ownership-taking APIs that still use raw pointers.</pre>
