Bug: _GraphRuntimeCodegen missing

Hi, I am using autoTVM to tune, but get a error:

AttributeError: module ‘tvm.relay.build_module’ has no attribute ‘_GraphRuntimeCodegen’

I had used this model some weeks ago, it worked well. Then I pull new commits today. So maybe some commits brings bug, and I find graph_runtime_codegen.py changes a lot. Can you check this error or should I roll back ?

Try rebuilding TVM. GraphRuntimeCodegen moved to C++ recently.

Thanks. I will try it.
