          REGRESSION: Selection bug in new text fields when selecting past the first letter

        Test: editing/selection/select-from-textfield-outwards.html

        * editing/Selection.cpp:
        (WebCore::Selection::adjustForEditableContent): Added code to handle the case
        where the selection starts (resp. ends) in the last (resp. first) visual position
        inside an editable root.
        * editing/htmlediting.cpp:
        (WebCore::comparePositions): Fixed the case of comparing a position inside a shadow
        tree with a position in the shadow ancestor.
        * rendering/RenderBlock.cpp:
        (WebCore::RenderBlock::positionForCoordinates): For coordinates outside a replaced
        object, return the position just before (after) the element if the coordinates are above or
        to the left (below or to the right).
        * rendering/RenderObject.cpp:
        (WebCore::RenderObject::caretMaxOffset): Changed to return 1 for replaced objects.
        * rendering/RenderText.cpp:
        (WebCore::RenderText::positionForCoordinates): Changed to return the last position
        in the lowest text box if the y coordinate is below all text boxes.
