Message:

[Refactoring] Accessing Node::m_document should be minimized.
​https://bugs.webkit.org/show_bug.cgi?id=73800

Patch by Hajime Morrita <​morrita@chromium.org> on 2011-12-06
Reviewed by Kent Tamura.

No new tests. No behavioral change.

Replaced m_document reference with the document() accessor
or temporaril variables. This is a preparation for using
m_document space to point a shadow root pointer.
