Fixed by Aldy's r12-4790-g4b3a325f07aceb

  Remove VRP threader passes in exchange for better threading pre-VRP.

  This patch upgrades the pre-VRP threading passes to fully resolving
  backward threaders, and removes the post-VRP threading passes altogether.
  With it, we reduce the number of threaders in our pipeline from 9 to 7.
