Makes sense. We possible extensions that come to mind:
- an extension for "transformations of loop-like ops": `apply_licm`, `hoist_loop_invariant_subsets`
- an extension for all "MLIR core transformations": `apply_licm`, `apply_patterns`, `apply_conversion_pattern`, `hoist_loop_invariant_subsets`, `apply_dce`, maybe I missed a few more

I would prefer the second one, what do you think? We could call it `Dialect/Transform/CoreTransformsExtension/CoreTransformsExtension.cpp`. (Or if you know a better name...)
