LivePhysRegs: Fix addLiveOutsNoPristines() for return blocks past PEI

- addLiveOutsNoPristines() needs to add callee saved registers that are
  actually saved and restored somewhere to the set (they are not
  pristine).
- Cleanup/rewrite the code for addLiveOuts()/addLiveOutsNoPristines().

This fixes the problem from D32156.
