Fix the malloc zone introspection functions so that malloc_zone_statistics does not give
bogus output in an application that uses JavaScriptCore.

• kjs/CollectorHeapIntrospector.cpp: (KJS::CollectorHeapIntrospector::statistics): Return statistics about memory allocated by the collector.
• kjs/CollectorHeapIntrospector.h:
• wtf/FastMalloc.cpp: Zero out the statistics. FastMalloc doesn't track this information at present. Returning zero for all values is preferable to returning bogus data.
