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
