        Bug 23109: REGRESSION: Backwards search in a long document matches incorrectly
        https://bugs.webkit.org/show_bug.cgi?id=23109

        Test: fast/text/find-backwards.html

        * editing/TextIterator.cpp:
        (WebCore::SearchBuffer::append): Fix incorrect size passed to memcpy.
        (WebCore::SearchBuffer::search): Handle case where we have an empty buffer but
        we're at a break; must not try to search because ICU will give us an error.
        Fix incorrect size passed to memcpy and memmove.
        (WebCore::findPlainText): Fix case where we found a match and need to search
        again because we want to find the last match. We need to try again without
        adding any more text or handling the break before moving on.
