Changed it to use `hasUnrollTransformation()` per Michael's comment. Note that `hasUnrollTransformation` does not take `llvm.loop.unroll.runtime.disable` into account. I think that's ok for now, since clang doesn't seem to be generating that MD and we only use it for marking epilogue loops. We could add that in the future as a separate patch, if the need arises.
