* method.h: introduce rb_callable_method_entry_t to remove 

rb_control_frame_t::klass.
  [Bug #11278], [Bug #11279]
  rb_method_entry_t data belong to modules/classes.
  rb_method_entry_t::owner points defined module or class.
    module M
      def foo; end
    end
  In this case, owner is M.
  rb_callable_method_entry_t data belong to only classes.
  For modules, MRI creates corresponding T_ICLASS internally.
  rb_callable_method_entry_t can also belong to T_ICLASS.
  rb_callable_method_entry_t::defined_class points T_CLASS or
  T_ICLASS.
  rb_method_entry_t data for classes (not for modules) are also
  rb_callable_method_entry_t data because it is completely same data.
  In this case, rb_method_entry_t::owner == rb_method_entry_t::defined_class.
  For example, there are classes C and D, and incldues M,
    class C; include M; end
    class D; include M; end
  then, two T_ICLASS objects for C's super class and D's super class
  will be created.
  When C.new.foo is called, then M#foo is searcheed and
  rb_callable_method_t data is used by VM to invoke M#foo.
  rb_method_entry_t data is only one for M#foo.
  However, rb_callable_method_entry_t data are two (and can be more).
  It is proportional to the number of including (and prepending)
  classes (the number of T_ICLASS which point to the module).
  Now, created rb_callable_method_entry_t are collected when
  the original module M was modified. We can think it is a cache.
  We need to select what kind of method entry data is needed.
  To operate definition, then you need to use rb_method_entry_t.
  You can access them by the following functions.
  * rb_method_entry(VALUE klass, ID id);
  * rb_method_entry_with_refinements(VALUE klass, ID id);
  * rb_method_entry_without_refinements(VALUE klass, ID id);
  * rb_resolve_refined_method(VALUE refinements, const rb_method_entry_t *me);
  To invoke methods, then you need to use rb_callable_method_entry_t
  which you can get by the following APIs corresponding to the
  above listed functions.
  * rb_callable_method_entry(VALUE klass, ID id);
  * rb_callable_method_entry_with_refinements(VALUE klass, ID id);
  * rb_callable_method_entry_without_refinements(VALUE klass, ID id);
  * rb_resolve_refined_method_callable(VALUE refinements, const rb_callable_method_entry_t *me);
  VM pushes rb_callable_method_entry_t, so that rb_vm_frame_method_entry()
  returns rb_callable_method_entry_t.
  You can check a super class of current method by
  rb_callable_method_entry_t::defined_class.
* method.h: renamed from rb_method_entry_t::klass to
  rb_method_entry_t::owner.
* internal.h: add rb_classext_struct::callable_m_tbl to cache
  rb_callable_method_entry_t data.
  We need to consider abotu this field again because it is only
  active for T_ICLASS.
* class.c (method_entry_i): ditto.
* class.c (rb_define_attr): rb_method_entry() does not takes
  defiend_class_ptr.
* gc.c (mark_method_entry): mark RCLASS_CALLABLE_M_TBL() for T_ICLASS.
* cont.c (fiber_init): rb_control_frame_t::klass is removed.
* proc.c: fix `struct METHOD' data structure because
  rb_callable_method_t has all information.
* vm_core.h: remove several fields.
  * rb_control_frame_t::klass.
  * rb_block_t::klass.
  And catch up changes.
* eval.c: catch up changes.
* gc.c: ditto.

* vm_backtrace.c: ditto.
