optutils.SetNodeSucessors improvement
[setnodesuccessors.patch](/uploads/a8fabeb3aa79b0e386c826d993116313/setnodesuccessors.patch)
Sorry for all this spam, I just sort of believe in these 0.999¹⁰⁰⁰ things, you know.
This patch speeds up `optutils.SetNodeSucessors` by a lot and the entire `-O3` compilation very slightly (0.02%). Speed up is mainly from the fact that average `SetNodeSucessors` ends up not using `BreakContinueStack` at all (90% of the time in my codebase) so efforts of setting up and tearing down some fancy structure for it often go in vain.
