        - change Document to hold onto Frame* instead of FrameView*

        This is an architectural cleanup and a prerequisite to fixing citibank login
        in an architecturally sound way.

        Some fixups for the page cache:

        * history/CachedPage.cpp:
        (WebCore::CachedPage::restore): Add an assert that the document's view
        matches the cached page's view - this needs to be true by the time this
        function is called.
        (WebCore::CachedPage::clear): Change assert to require frame matching, not
        view matching.
        * history/CachedPage.h:
        (WebCore::CachedPage::view): Add a way to get the view out.
        * loader/FrameLoader.cpp:
        (WebCore::FrameLoader::begin): pass Frame, not FrameView, when creating document
        (WebCore::FrameLoader::open): restore view based on CachedPage, not Document.

        Remaining changes are just straightforward updates based on which
        pointer is held or passed:
