I don't see any reason why it should not work on Windows. But there was a failing Windows buildkite, so I temporarily disabled the test. I will try again to see if it was a transient issue. If the issue still persists, I will add a comment indicating that the option should work on Windows, but that the original author did not have a means to test it and, therefore, disabled it. Since some of the tests require a full toolchain to be present, @MaskRay suggested being conservative about where the tests were run.

I have generally kept `CLOption` and `DXCOption` when the original did not explicitly specify anything for compatibility.
