[Text Autosizing] Cleanup change: converter the pointer argument to be a reference...

non-null pointer is always expected.
https://bugs.webkit.org/show_bug.cgi?id=109079

Patch by Anton Vayvod <avayvod@chromium.org> on 2013-02-09
Reviewed by Kenneth Rohde Christiansen.

Cleanup change, no need to add new tests or modify the existing ones.

* rendering/TextAutosizer.cpp:

Changed parameter from a pointer to a reference in the methods below.

(WebCore::TextAutosizer::processSubtree):
(WebCore::TextAutosizer::processCluster):
(WebCore::TextAutosizer::processContainer):
(WebCore::TextAutosizer::isNarrowDescendant):
(WebCore::TextAutosizer::isWiderDescendant):
(WebCore::TextAutosizer::isAutosizingCluster):
(WebCore::TextAutosizer::clusterShouldBeAutosized):
(WebCore::TextAutosizer::measureDescendantTextWidth):

* rendering/TextAutosizer.h: updated method prototypes.
