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.
