@reviewers A note regarding the changes in Clang.

This patch introduces a Flang option (`-test-io`), that should not be available/visible in Clang. AFAIK, there's no precedent of that, hence `options::NoClangOption` is introduced. This is discussed in more detail here: http://lists.llvm.org/pipermail/cfe-dev/2020-October/066953.html.
