`CloneFunction.cpp` currently says "It is only legal to clone a function if a block address within that function is never referenced outside of the function.".
This is only the case for cloning into the same module (this patch handles this), for cloning/moving into a different module, it is actually okay.

I'm still working on a unit test but want to hear reviewer's opinion earlier since I'm not why it is not handled before, no valid use case or some constraints.
