Rebased atom-bypass-slow-division*.ll tests on https://reviews.llvm.org/D28469.

Didn't rebase slow-div.ll because in the next patch I would add several RUN lines into the test which produce similar but not exactly the same assembly. So, I decided to check here only whether the transformation is applied or not.
