   The script is simply test_pass_partition_graph.py is TVM tests. 
   Replacing `mod=WhiteListAnnotator(["add","substract","multiply"], "ccompiler")(mod)`
   with `mod=WhiteListAnnotator(["nn.conv2d"], "ccompiler")(mod)`
   
   Then simply calling `relay.build(mod, target, params)`
   
   Crash happens because it only knows about add, substract, multiply and nothing else. 
   ```
   File "../src/relay/backend/contrib/codegen_c/codegen.cc", line 124
   TVMError: Unrecognized op
   ```
   
   I was under the assumption that using ccompiler would reuse TVM for x86 on the subgraph, similar to what on_device() does.
