Speculative fix for segv destroying CPDF_PageObjectHolder::m_GraphicsMap
We speculate that the bug that makes the comparison operator irreflexive might be the cause of the segv on windows production code, should a NaN sneak into the GraphicsData struct. In any event, should this happen, the tree won't be correct with some nodes erroneously replaced. Add a test which fails prior to the patch, but alas does not elicit the segv. Also move operator<() methods to .cpp file corresponding to .h file in which they are delcared.
