This causes a ~4% regression on sksl_large, but some of that can be bought back in two ways: 1) Removing (now unnecessary) cloning of program elements 2) Hoisting the new analysis passes, with (nontrivial) logic to update/maintain the call counts as we edit IR. Also, this fixes bugs where we were emitting functions that had "calls" from no-longer called functions.
