We can't consistently rewire the successor blocks of an unreachable node to disconnect them from the graph when we are trying to maintain the schedule. Instead simply leave the code there. As a future optimization we could add a proper scheduled dead code elimination phase which can deal with this. As a side-effect, one of the tests sees a int64 DeadValue, so add support for that in the instruction selector.
