        https://bugs.webkit.org/show_bug.cgi?id=56407

        Fixing the creation of incorrect ranges from TextIterator due to passing node/offset pairs that
        weren't parent-anchored. Also changing canHaveChildrenForEditing to properly handle nodes that
        have had children appended to them that editing wouldn't normally allow.

        Tests: editing/style/iframe-onload-crash-mac.html
               editing/style/iframe-onload-crash-unix.html
               editing/style/iframe-onload-crash-win.html

        * editing/TextIterator.cpp:
        (WebCore::TextIterator::rangeFromLocationAndLength): Passing parent-anchored values to range.
        * editing/htmlediting.cpp:
        (WebCore::canHaveChildrenForEditing): Adding a condition that the nodes don't already have children
        for hr and datagrid, as you can append any node to another using javascript.
