Brian Osman 2e25ff436a Directly compute call counts, rather than mutating state
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.
