Source/WebCore:
Test: fast/dom/modify-node-and-while-in-the-callback-too-crash.html
* dom/DocumentOrderedMap.cpp: defensive fix to avoid use after free

(WebCore::DocumentOrderedMap::remove):
* html/HTMLImageElement.cpp:
(WebCore::HTMLImageElement::insertedInto):
* loader/ImageLoader.cpp:
(WebCore::ImageLoader::updateFromElement): setting m_failedLoadURL makes
repeated updateFromElement calls return early.
