Prints libkern/IOKit memory-debugging statistics: per-class instance counts via OSMetaClass::printInstanceCounts, followed by the accumulated debug counters for instance-variable kalloc, malloc, container kalloc, and IOMalloc allocations (debug_ivars_size, debug_malloc_size, debug_container_malloc_size, debug_iomalloc_size), written with IOLog. The counters are maintained only when OSALLOCDEBUG accounting is compiled in.
