<h3>Log Message</h3>
<pre>New clang warns about boolean checks for |this| pointer in RenderObject debug methods
<http://webkit.org/b/136599>
Reviewed by Zalan Bujtas.
Ignores the following static analyzer warnings:
Source/WebCore/rendering/RenderObject.cpp:1465:10: error: 'this' pointer cannot be null in well-defined C++ code; pointer may be assumed to always convert to true [-Werror,-Wundefined-bool-conversion]
if (!this) {

Source/WebCore/rendering/RenderObject.cpp:1584:10: error: 'this' pointer cannot be null in well-defined C++ code; pointer may be assumed to always convert to true [-Werror,-Wundefined-bool-conversion]
if (!this)
~^~~~
* rendering/RenderObject.cpp:
(WebCore::RenderObject::showRenderObject):
(WebCore::RenderObject::showRenderSubTreeAndMark):
Add "#pragma clang" preprocessor macros to ignore this warning
since the code is only compiled for Debug builds. Also add a
pragma for the pragma so older clangs don't complain about an
unkonwn pragma.</pre>
