I have always found it frustrating that the man page for `clang` did not have all the options, but that might be me. I don't think that the pages for Flang's design belong in a man page though.

We may want to consider auto-generating a command-line reference and having that in the man page, but that is a broader, and potentially longer, discussion that should not hold up this PR.
