Log Message:
-----------
AX: AXObjectCache::onDocumentRenderTreeCreation can call getOrCreate at times
when it's not safe to do so, which causes CheckedPtr crashes

rdar://165274244
Reviewed by Joshua Hoffman.
AXObjectCache::onDocumentRenderTreeCreation is downstream of
DocumentLoader::finishedLoading(), and that is not a safe
time to call getOrCreate, which requires clean layout and style. Defer handling
of these new render trees via a new
AXObjectCache::m_deferredDocumentsWithNewRenderTrees member variable.
