* Add new client request VALGRIND_HG_CLEAN_MEMORY_HEAPBLOCK. This is like VALGRIND_HG_CLEAN_MEMORY but doesn't take an address range. Instead it takes a single argument which is supposed to be a pointer to the start of, or anywhere within, a heap allocated block. Helgrind then finds the block and paints it as belonging to the calling thread. This is needed for correctly describing the behaviour of threadsafe reference counting when applied to classes involving inheritance of release methods or involving multiple inheritance. * Add statistics counters for all basic VTS operations (tick, join, cmpLEQ, cmp_structural). * Rewrite VTS__cmp_structural to be much faster. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@11123
