I also touched the lib_call function in the cg_clif repo. I would prefer syncing that first to prevent conflicts during a sync.

Happy to rebase over a cranelift sync if it can land soon. I'd prefer not to make it a blocker, because other PRs are waiting on this one, and I expect it will take a while to actually land (even if we're lucky and there are no more issues, it's going to hit the 6h CI timeout...)
