[PATCH] D78980: Elaborate more on --rocm-path flag.

[Matt Arsenault via Phabricator via cfe-commits]

arsenm created this revision.
arsenm added reviewers: yaxunl, t-tye.
Herald added a subscriber: wdng.

I'm not sure what the conventions are for this documentation. The
format seems limiting. I don't see how to refer to other flags, or
mark flags as deprecated. The rst I believe these generate seems to be
in source, and out of date.
