the controlling plans so that they don't lose control. Also change "ThreadPlanStepThrough" to take the return StackID for its backstop breakpoint as an argument to the constructor rather than having it try to figure it out itself, since it might get it wrong whereas the caller always knows where it is coming from. rdar://problem/11402287 llvm-svn: 156529
