Does any of you use print_class_statistics?
It seems most of these variables were set-but-unused even in gcc-2.95 (!). So
I think we can safely 86 all of this. Or is the "n_vtables" info interesting
in any way?
Bootstrapped/regtested on x86_64-linux, ok for trunk?

* class.c: Remove unused global variables.
(build_primary_vtable): Don't gather statistics.
(print_class_statistics): Remove.
* cp-tree.h (print_class_statistics): Remove.
* tree.c (cxx_print_statistics): Don't call print_class_statistics.
