================
Comment at: lib/Transforms/Vectorize/LoopVectorizationLegality.cpp:438
   // Reductions, Inductions and non-header phis are allowed to have exit users. All
   // other instructions must not have external users.
   if (!AllowedExit.count(Inst))
----------------
This would be trivial if we realize that outside user must be in a loop-closed phi node for a valid LCSSA, IIUC @sebpop ?
