implemented irout: backedges.  Added one field to ir_graph, one to ir_node.
  Implemented state management for irgraphs:  see irgraph.h.
  Must now call finalize_cons() after graph construction!!C

  Adapted End node.
  Adapted Phi constructors so that memory phis are added.
  Adapted Cond optimization: add block to End.
  Adapted dead node elimination: compation of Ends predecessors
  Adapted inlineing:  remember keepalives of inlined graph.
  Added informative strings to asserts in irvrfy.

  Added volatile flag to entity, order flag to array.
  Added a set of assertions.
  Added access function set_class_members()  dded info to type nodes

mfortable" construction interface by some methods
  serving as simple shortcuts.

  Added a class type to irgs.  This class type is to be used as owner
  for local entities of the procedure. This are all entities allocated
  for each execution of the procedure.
  The class type is allocated automatically by new_ir_graph().  Access
  routines to get this type are in irgraph.h.
  We chose a class type as this allows to represent "inner" procedures
  as, e.g., in Pascal.
  Adapted array-stack-example.

  Changed SSA constuction for exception control flow.
  If PRECISE_EXC_CONTEXT is used Phi nodes will use the values
  valid when the execption operation was allocated.  This increases
  the memory consuption of the construction algorithm by
  n_loc * #fragile_ops.

  Added functionality to irgmod:
  * collect all Phi nodes as link-list in th eBlocks link field
  * collect all Proj nodes as link-list in node productin the tuple
  * Seperate a Block into two
  Added inlining transformation in irgopt.h
  Improved output of dump_ir_block_graph.  Now also dumps nodes that
  don't belong to a block.
  Added flag opt_unreachable_code, opt_inline.
  Changed irvrfy so that it accepts nodes with Bad predecessors.
