Being in an anonymous namespace just means you cannot invoke the methods
of the pass directly. Given a pointer to an object of that pass, however,
you can invoke virtual methods and otherwise use the pass.
To get a pointer to an instance of the mem2reg pass, just call
createPromoteMemoryToRegister(), declared in
