[lldb-dev] Auditing dotest's command line options

[Zachary Turner via lldb-dev]

I have updated the list of command line options with a proposed action.  It
looks like exactly half of the command line options can be deleted, which
is going to be a huge win for being able to understand what the test suite
does and how to use it effectively.  Please take a look at the updated
spreadsheet and make final comments.  Last change to keep an option if I've
marked it as delete.

For a few of the ones people wrote that they use the option, but it seems
like the same functionality is provided by a different option.  I marked
these as PREFER DELETE, but feel free to comment here if you still think it
should remain.  I'll tackle those last and make sure there's consensus that
it's ok to delete them before doing so.

If there's no otehr comments, I plan to start working on this on Wednesday.
