LiveVariables is the optimized and tested way to get variable
liveness information (it's used by register allocation).
Unfortunately it requires a MachineFunction to work - so you'll
either need to lower to one of the built-in targets or add your
own target to acquire access to this pass.<br>

Is it possible to lower to a target from a ModulePass just to get
the LiveVariables?<br>
