It is only in our downstream branches.  I stripped out support in llvm.org
lldb per our other threads.

We could do that.  Internally we also use that for builds other than Xcode,
so whatever solution I use (which is currently what I had proposed earlier
but now have only in our branches) really needs to work for more than Xcode.

That's a great compromise, I appreciate your thoughts on that.  Since I
need it for more than Xcode, right now the solution I have in our branch is
working okay.

That structure may make sense.  That could live in llvm.org.  Then for
other OSes where I want similar behavior, I could just keep those parts in
our branch.  Ultimately I'd end up with multiple copies of the wrapper (for
any OS we may build for internally), but I could symlink so that's not
really any kind of issue.

This might work.

I could see that layout making sense.  If we did something like that, I
think I'd separate moving the lldb.xcodeproj and lldb.xcworkspace from the
creation of the contrib folder.  (i.e. I'd start with the wrapper part in
there, and have the others move there at lower priority as a scheduling
thing --- there's a bit of work to make the workspace/project change but
should be totally doable).

I think I like the idea since it reduces the number of merge issues I'd
have to deal with.
