In `opt.cpp` it checks the order they are passed on the command line and adds them in that order (including `-O#`).

Ah, my bad, thanks for clarifying! However,

  ./bin/opt -S -O1 loopversioningLICM1.ll -o O1.ll
  ./bin/opt -S -loop-versioning-licm -licm O1.ll

does not seem to be working for me for some unknown reasons. I'll dive into it more deeply tomorrow.
Thanks for your time.
