Reinstate Addrcheck.  Some of the tests fail -- some of the leak ones
because the added VG_(find_root_memory)() is just a stub.  And there's a
problem with overlap checking that I haven't worked out yet.  Still it's a
start.  The commit also brings Memcheck back into the build process,
although mc_main.c is entirely commented out at the moment.
