exception handling related changes:
* changed blockPredecessors to list of Instructions, instead of Blocks
* removed explicit predecessor management in BlockBegin, now using predecessors from Graph structure
* replaced generated LIR exception entries with exception dispatch chains in IR
* added Unwind and ExceptionDispatch instructions
* removed ExceptionEntry flag in BlockBegin and all code depending on it
* removed exceptionHandler list from Instruction, replaced by exception Edge on Invoke and Throw
* replaced list of ExceptionHandlers with single exception edge in debug info
misc:
* changed GraphvizPrinter layout (smaller ports on large nodes)
* removed defunct run config
