LGTM with a couple of minor nits.



================
Comment at: llvm/lib/Transforms/Vectorize/LoopVectorize.cpp:1074
       // either drop them directly if the recipe already models the flags or
       // collect them in a set.
       // TODO: Migrate all relevant recipes to hold their own flags.
----------------
Update above comment and remove TODO below?


================
Comment at: llvm/lib/Transforms/Vectorize/LoopVectorize.cpp:1076-1078
+      if (auto *OpWithFlags = dyn_cast<VPRecipeWithIRFlags>(CurRec)) {

+      } else {
----------------



================
Comment at: llvm/lib/Transforms/Vectorize/LoopVectorize.cpp:2849

-  if (State.MayGeneratePoisonRecipes.contains(RepRecipe))
-    Cloned->dropPoisonGeneratingFlags();
+  Cloned->dropPoisonGeneratingFlags();

----------------
Above is redundant and should be dropped?
