Sweep interpreter caches using checkpoint during GC
Interpreter caches are mutator thread-local caches. Currently, the way
GC sweeps these caches breaks that invariant and requires
synchronization for correct behavior.
In this CL we take a different approach of sweeping the caches
during GC using checkpoint (or in a stop-the-world pause),
eliminating the need for synchronization.
