oh, @tbaederr I see you've done some overlapping work over in
https://github.com/llvm/llvm-project/pull/68288 : I'll make time to review that
and see what ought to happen to dovetail these patches.

Happy new year!
An update from my end: I've made what feels like good progress on refactoring

dynamic instruction count (especially for large types). There's still a little
more I'd like to do there,
