Did a few things:
        
- Options::showDFGDisassembly now shows OSR exit disassembly as well.
        
- Phi node dumping doesn't attempt to do line wrapping since it just made the dump harder
  to read.
        
- DFG graph disassembly view shows a few additional node types that turn out to be
  essential for understanding OSR exits.
        
Put together, these changes reinforce the philosophy that anything needed for computing
OSR exit is just as important as the machine code itself. Of course, we still don't take
that philosophy to its full extreme - for example Phantom nodes are not dumped. We may
revisit that in the future.
