Where r12 is restored? It contains coop base.

I forgot to add the reinit_heapbase call. I've updated the webrev. Surprisingly my tests didn't crash. I ran some more tests and found a problem with stack walking for throw_NullPointerException_at_call. I'm looking into it.

I also noticed that two stubs were dead which made an extra argument dead so I cleaned that up at the same time. Tested on linux-amd64 with new regression test and failing tests from report.
