Improve "bad parent" and "bad child list" assertions in line boxes
https://bugs.webkit.org/show_bug.cgi?id=125656
Reviewed by Sam Weinig.
* rendering/InlineBox.cpp:
(WebCore::InlineBox::root): Use parent() function with assertions rather than
using m_parent function, which skips the assertions.
* rendering/RenderText.cpp:
(WebCore::RenderText::removeAndDestroyTextBoxes): Call invalidateParentChildLists
if we are in the optimized document-destruction code path and destroying children
without removing them from their parents.
* rendering/RenderTextLineBoxes.cpp:
(WebCore::RenderTextLineBoxes::invalidateParentChildLists): Added.
* rendering/RenderTextLineBoxes.h: Added invalidateParentChildLists.
