   > This seems like a great change! Have you done any tests on how it affects performance?
I'd love to know how much this speeds things up.
   
   I measured vectorization benefits on a vector add micro-benchmark in this PR
   
   https://github.com/apache/incubator-tvm/pull/4968
   
   The speedup could be as high as 20+%.
   
   This is a missing feature to enable PR4968.
