[C++][Gandiva] Loop vectorization broken in IR optimization

    Details

      Description

      Yibo Cai pointed out in the mailing list that this is broken.

       
      I found that there is something in the last change to llvm_generator.cc that broke the auto vectorization.

      If I undo this one patch, I can see the vectorization happen with Yibo Cai's test.
