90a6dce041 * method.h: introduce new method type VM_METHOD_TYPE_CFUNC_FAST.
This method is similar to VM_METHOD_TYPE_CFUNC methods, but
  called cfunc without building new frame (does not push new control
  frame). If error is occured in cfunc, the backtrace only shows
  caller frame and upper.
  This kind of methods can be added by rb_define_method_fast().
  This feature is similar to specialized instructions (opt_plus, etc),
  but more flexible (but a bit slower).
* class.c (rb_define_method_fast): added.
  Maybe it will be renamed soon.
* vm_insnhelper.c (vm_call_method): support method type
  VM_METHOD_TYPE_CFUNC_FAST.
* proc.c (rb_method_entry_arity): catch up new method type.
* vm_method.c (rb_add_method_cfunc_fast): added.

2285a8d813 * class.c, gc.c, object.c, variable.c, vm_insnhelper.c,
include/ruby/ruby.h: separate RCLASS_CONST_TBL from RCLASS_IV_TBL.
  RCLASS_IV_TBL has contained not only instance variable table but
  also constant table.  Now the two table are separated to
  RCLASS_CONST_TBL and RCLASS_IV_TBL.  This is a preparation for
  private constant (see [ruby-dev:39685][ruby-core:32698]).
