Review comment:
       to be consistent with the VoidType, perhaps we can use Void here? See also https://github.com/apache/incubator-tvm/blob/master/include/tvm/ir/type.h#L375
   
   Also need to update GetRuntimeType and GetType here https://github.com/apache/incubator-tvm/blob/master/include/tvm/tir/op.h#L60
