Fix print of Path nodes when using OPTIMIZER_DEBUG

michaelpq · michaelpq · commit 49d506dd2162 · 2018-07-19T09:55:15.000+09:00
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.
