The basic idea is: exploits data dependency to control the execution order
of side-effect operations, and keep the semantics of ANF unchanged.

The ControlDepend primitive is removed and there are two primitives added:

1. UpdateState:
```
  a = Assign(para, value)
```
became:
```
  a = Assign(para, value, u)
  u = UpdateState(u, a)
```

2. Load:
```
  x = Add(para, value)
```
became:
```
  p = Load(para, u)
  x = Add(p, value)
  u = UpdateState(u, p)
```

normalize codes of session

2. erase kAttrChildGraph after finish using

2.attach original inputs to graph when replace call and switch to
labelgoto and labelswitch

merge me commit for remove inline

deal witch multiple cases of switch in ConstructKernelGraph

deal with switch and call cases in ConstructKernelGraph

fix bug and rebase master

ConstructKernelGraph adapte to remove inline

fix InsertMultipleAssignToGraph bug

add graph input to new graph which is created for switch input

replace CreateNewParameterFromCNode to NewParameter in order to set new
parameter's abstract and kernel_info

avoids create a new switch repeatedly when the cnode is a call switch without real input
