  [NFCI] Introduce `ICmpInst::compare()` and use it where appropriate

As noted in https://reviews.llvm.org/D90924#inline-1076197
apparently this is a pretty common pattern,
let's not repeat it yet again, but have it in a common place.

There may be some more places where it could be used,
but these are the most obvious ones.
