precompute pass is not working for given test cases. Almost every function don't have any constraints on parameter range. So we have to change sprint 2 plan temporarily.
LoopSumPass is being implemented well. Currently it manages simple loop without phi node inside IR, but maybe we can handle complex situation in this pass.
Mem2StackPass has to be controlled delicately. Stack pointer is hard to manage since RA is blackbox to us.
Utility like benchmark scripts, command line option is needed. @sharaelong will implement it.
