Basically, disable everything except the eh_frame unwind plan, as that's the only one which supports this right now. The other plans are working with now trying the interpret everything in between the function parts as a part of the function, which is more likely to produce wrong results than correct ones. I changed the interface for object file plans, to give the implementations a chance to implement this correctly, but I haven't actually converted PECallFrameInfo (its only implementation) to handle that. (from the looks of things, it should be relatively easy to do, if it becomes necessary) I'm also deleting UnwindPlan::GetFirstNonPrologueInsn, as it's not used, and it doesn't work for discontinuous functions.
