GoLang support and complex.go example

While I can build the sample directory in tvm/golang and the simple.go example and pack_func.go etc all run okay, when running the complex.go example, I get a TVM invariant was violated during the execution of TVM during module execution.

Note: I do run gen_mobilenet_lib.py prior to running complex.go and all expected files are present. the error is generated when the Module is executed.

Before I post the full error and stacktrace - I would like to make sure I am using a supported version of Golang. Which version of Go is currently supported for GoTVM and the sample directory?
