- first round of preparation for Hyatt's "lazy minMaxWidth" change
          http://bugs.webkit.org/show_bug.cgi?id=13431

        This patch limits itself to renaming and making other super-simple
        changes so that the above change will be smaller and easier to review
        and understand.

        Rename:

            calcHorizontalMinMaxWidth -> calcHorizontalPrefWidths
            calcMinMaxWidth -> calcPrefWidths
            calcMinMaxWidthInternal -> calcPrefWidthsInternal
            calcVerticalMinMaxWidth -> calcVerticalPrefWidths
            setNeedsLayoutAndMinMaxRecalc -> setNeedsLayoutAndPrefWidthsRecalc
            trimmedMinMaxWidth -> trimmedPrefWidths

            RenderObject::m_maxWidth -> RenderObject::m_maxPrefWidth
            RenderObject::m_minWidth -> RenderObject::m_minPrefWidth
            RenderObject::maxWidth() -> RenderObject::maxPrefWidth()
            RenderObject::minWidth() -> RenderObject::minPrefWidth()

        Replace m_minMaxKnown, minMaxKnown(), and setMinMaxKnown() with
        m_prefWidthsDirty, prefWidthsDirty(), and setPrefWidthsDirty(),
        a boolean with the opposite sense.

        Convert some uses of if statements into "max".

        Change many uses of layer() to hasLayer(). For now it's just a boolean
        version of layer(), but Hyatt's patch makes it faster by using a bit.

        Added a guard to use of axObjectCache() to make RenderObject destruction
        a little faster for the normal case.

        Removed some assertions that will be removed in Hyatt's patch.

        Made some functions const that will be const in Hyatt's patch.

        Put in some revised comments from Hyatt's patch.

        Removed an unneeded nil check from RenderListMarker::setStyle.

        Moved RootInlineBox::setHorizontalOverflowPositions and
        RootInlineBox::setVerticalSelectionPositions to the RootInlineBox.h
        header and marked them inline.
