* class.c, variable.c, gc.c (rb_class_tbl): removed.

* vm.c, vm_core.h (rb_vm_add_root_module): added to register as a
  defined root module or class.
  This guard helps mark miss from defined classes/modules they are
  only refered from C's global variables in C-exts.
  Basically, it is extension's bug.
  Register to hash object VM has.
  Marking a hash objects allows generational GC supports.
* gc.c (RGENGC_PRINT_TICK): disable (revert).
