-CinnLaunch Operator.
-
-This operator is used to launch CINN(https://github.com/PaddlePaddle/CINN/blob/develop/README.md)
-to compile a graph and execute the compiled object.
-
-Both input and output of this operator are a set of variables
-which are input and output of the graph respectively that will be
-compiled and executed in this operator.
-In addition, there is an attribute named 'compilation_key' should be
-set necessarily to get corresponding ir::Graph object of the graph
-or its computation result.
-
-It accomplishes the computation of graph following several steps:
-  1. Fetch ir::Graph object from CinnCompiler using kCompilationKey
-  2. Compile the graph to a compiled object, and insert it to the
-     global cache so that we can directly query it from this cache next time
-     when shape of input variables are not changed at all.
-  3. Create and instantiate all variables used to execute compiled runtime program
-     if necessary according to the info(type,shape) included in the return scope.
-  4. Pack each tensor buffer of all above variables as execution arguments.
-  5. Launch execution of the runtime program with above arguments, then
-     the result would be output by writing value on underlying buffer address.
