Move the debug.hashstat sysctl tree under DIAGNOSTIC.  I measured the
debug.hashstat.rawnchash sysctl in particular as taking 7 milliseconds on
a 3GHz Intel Xeon (4x2) running 7.1.  It accounted for almost a quarter of
the total runtime of 'sysctl -a'.  It also performs lots of copyout's while
holding the namecache lock (this does not attempt to fix that).
