* class.c, constant.h, gc.c, method.h, object.c, variable.c, 

vm_insnhelper.c: use struct rb_constant_entry_t as entry of
  RCLASS_CONST_TBL.  RCLASS_CONST_TBL has contained VALUE of constant
  directly.  Now instead rb_const_entry_t is contained in
  RCLASS_CONST_TBL,  rb_const_entry_t is managed by malloc, and
  have not only the value itself but also visibility flag.
  This is another preparation for private constant (see
  [ruby-dev:39685][ruby-core:32698]).
