After some thought, I actually like the idea of making general LICM part of `greedyRewriter`/`canonicalizer`.
The plan will be:
* Add `doLICM` option to `GreedyRewriteConfig` (`false` by default)
* Have if enabled in `canonicalizer` pass (we can add a pass option to control it, if we really want it)
