initial commit, code tracing implemented
some SSA translation
can SSA first function, no phi functions yet
expr: duplicate AND
expr: expression pretty printing
insn: order next edges consistently

branch target goes last
ssa: do not follow calls
ssa: better statement ctor for reduced verbosity
expr: print const/var ops differently
expr: just don't...
insn: print without ugly prefix
ssa: add insn reference to statements
ssa: fixed comment on 0x91
insn disassembler: implement all opcodes from first function
definitions class
ssa: statement chain method

fixes comefroms for flag ops
ssa dump: initialized parameters are persistent

WTF?
expr: getallops() returns all operands of an expression
ssa: dead code elimination

quite buggy still
ssa dce: deal with more than one comefrom
