Sorry for the misunderstanding. What I meant was we won't need this test
anymore. There shouldn't be a case where we do `dxil-op-lower` without the
scalarization pass.
What I wan't is for the test I added in `split-double.ll` to be consolidated
into your splitdouble.ll tests and then you delete the `split-double.ll` file.
