Test fixes and rebase problems
Note that this removes a number of run-pass tests which are exercising behavior of the old runtime. This functionality no longer exists and is thoroughly tested inside of libgreen and libnative. There isn't really the notion of "starting the runtime" any more. The major notion now is "bootstrapping the initial task".
