Bump IC rebuild threshold to 30

* 40 seems to benefit but is too close to the JIT threshold of 50 so, picked a number in between. * This is all a bit random right now. We need do this more systematically anyway (recompile based on execution counts, size of scope, type of scope, cost of rebuilding/JITting, etc.) using some empirical measurements that feed into some cheap algorithm / state-machine.
