Fix print of Path nodes when using OPTIMIZER_DEBUG

Browse Source 
GatherMergePath (introduced in 10) and CustomPath (introduced in 9.5)
have gone missing.  The order of the Path nodes was inconsistent with
what is listed in nodes.h, so make the order consistent at the same time
to ease future checks and additions.
