I think that having a liboffload plugin would be nice, but I don't think we
should really base everything on top of this for a few reasons:

1) I think we already have a nice plugin interface specifically designed to
support out-of-tree platforms with StreamExecutor, and it wouldn't make a
lot of sense to force them to re-implement there stuff.

2) Some platforms may not want or be able to use the liboffload style
plugin.

It seems like if the OpenMP folks want to add a liboffload plugin to
StreamExecutor, that would be an awesome additional platform, but I don't
see why we need to force the coupling here.

My 2 cents.
