[WarnMissedTransforms] Do not warn about already vectorized loops. LoopVectorize adds llvm.loop.isvectorized, but leaves llvm.loop.vectorize.enable. Do not consider such a loop for user-forced vectorization since vectorization already happened -- by prioritizing llvm.loop.isvectorized except for TM_SuppressedByUser.
