Thanks Ayal @Ayal for pointing this out. I will move it with patch https://reviews.llvm.org/D80446
I thought the test was to address Bardia's and Florian's comments about needing "some actual instructions in the loop body, so there is something to predicate", so I added it to the test in this patch. I then only CHECK-ed for details of interest and thus omitted those covered by the other CHECKs.
