No, there was no mention of needing to run another pass to cause the crash; I just had instcombine in it since the other lines did. I found the bug when running llvm-test-suite with -mcpu=native, and on the particular core I had epilogue vectorization was used for one csa loop.

I'll move this back to LV but keep it in a separate file.
