When performing codegen at optnone, don't add alias analysis to the pipeline. We don't need it, but it causes an unnecessary dominator tree calculation. (There are still two more left...)

I've also moved the module verifier call to the top so that a bunch of disabled-at-optnone passes group more nicely.
