I'm trying to remove `lowerMod` from this pass. `createLowerModule` gets the
triple exactly the way you did it before. The fact that this even needs to know
the triple kind of implies that this lowering should be happening in an earlier
pass but let's leave it here for now and move it when we have more target
lowering implemented.
