I think we want to drop the advice to check command line arguments because it
could also be the result of using pragmas as well. I think we can lean on
calling it out as undefined behavior to tell the user that something is wrong
somewhere.
I think we could instead add some documentation to `DiagnosticDocs.td` about
the command line and pragmas potentially impacting things, and then link those
docs with the `nan-infinity-disabled` warning group.
