See my comment in https://reviews.llvm.org/D45733. Sorry that I didn't get a chance to review/discuss this sooner.

I doubt the premise that this pattern should exist in the first place, so I suspect we don't want to add logic to transform it. But if it does exist, then and/and/or is the best canonical form for the IR - it's better for bit-tracking analysis and better for codegen.
