llvm dev - Jun 2018 - Converting Value* to GenericValue for runFunction?

I have a list of arguments for a CallInst that I would like to pass to
another compiled LLVM function with execEngine->runFunction(). How can I
convert all the Values to GenericValues for runFunction?

Some example arguments are types %struct.CPUARMState*
%env, %struct.ARMCPRegInfo*, and i64.

I can use LLVMCreateGenericValueOfPointer for the pointer arguments, but I
don't know how to convert the i64.

Thanks!

It seems like what I want is `GenericValue
ExecutionEngine::getConstantValue(const Constant *C)`, but this is a
protected function. Is there another proper way to do this?
