I've spoken with Thomas. He's happy to take GCN patches there, or GCN 
related patches anyway, so that's an option.

I can use it as my upstream, or push my changes directly.

The more I think about this, the more I'm coming to the conclusion that 
nobody but me really cares about GCN for GCC 8, and nobody cares about 
the development history, so I'm over-complicating my upstreaming plans.

I should just do what I need to do in my local repo, as before, and 
submit a somewhat flattened patch series for inclusion in trunk in the 
traditional manner, as soon as I have it.
