[Apache TVM Discuss] [Development] [API] Does the tvm has use-def chain?

[Allen via Apache TVM Discuss]

I take a look at the function StmtSimplifier::VisitStmt_ in simplify.cc, it 
don't use an api  similar to *getUser*  in llvm to get the user  op of store 
op. so my question: Is there similar api in tvm to get the def-use chain ? 
```
// eliminate useless stores
Stmt StmtSimplifier::VisitStmt_(const StoreNode* op) {
  Stmt stmt = Parent::VisitStmt_(op);
  op = stmt.as<StoreNode>();
  if (const LoadNode* load = op->value.as<LoadNode>()) {
    if (load->buffer_var.same_as(op->buffer_var) && 
ExprDeepEqual()(load->index, op->index)) {
      return Evaluate(0);
    }
  }
  return GetRef<Stmt>(op);
}
```
