like field reordering (possible problems cracker classes) or using ebp as normal register (broken
stack traces from dump_stack)
+ niln is also valid in a cse domain
* parameters passed by reference shall have a complexity >1
* load nodes from outer scopes shall have a complexity >1
* better cse debugging
+ more node types added to cse
* consider parameters passed by reference in cse
* take care of cse in parameters in simple cases
