- Introduce the concept of the graph state bitset: This is a set of flags that indicate the current "state" of a graph.
  (Used so far to indicate wether muxes are lowered and should not be touched anymore and wether architecture dependent mul and div with constant implementations are used)
  We should use this to indicate dom/loop/... consistency in the fututure
- fixed a bug where lower_mode_b was creating a "set" instruction with the help of a Mux. (Maybe we should create a new Node for this and not use a 0/1 mux?)

- changed handling of Mux nodes: these are now optimized using the iropt instead of additional runs in the if-conv
if-conv:
- through away analysis info only when graph was changed
- fixed handling of Raise
- removed useless dominator computation
- add some docu

- improved hash_SymConst(): no need for mode, handle labels right

Renamed get_Cond_defaultProj() to get_Cond_default_proj() for consistency. Added set_Cond_default_proj() and get_cond_kind_name(). Made get_cond_jmp_predicate_name() consistent with other enum name functions.
