Export TIR to json

Hi,

thanks for the reference to this function. I was not aware of it. However I tried it on a Module(c) and got this: { "root": 1, "nodes": [ { "type_key": "" }, { "type_key": "runtime.Module" } ], "b64ndarrays": [], "attrs": {"tvm_version": "0.9.dev0"} } This looks like only a very small overview. What we would like to have is really the full representation that the code generators get to write the code. Do I miss an option for this function to get more detailed output?
