Bug #6662: prepend した Class/Module が継承ツリー上にある Class/Module で ancestors に Class が入り込む

prepend した Class/Module で Module#ancestors の順番や Class が入り込む問題は r36241 で対処されましたが
まだ ancestors を呼ぶ Class/Module そのものではなくてその superclass や include している Module で
prepend を使っていると順番が include と同じになる & Class が入り込むようです。

module M; end
class C1
prepend M
end
class C2 < C1
end
C2.ancestors => [C2, C1, M, Class, Object, Kernel, BasicObject]

prepend: fix mixing with include

• class.c (rb_include_module): include modules after the origin.
• class.c (include_modules_at): skip prepended modules.
• class.c (rb_prepend_module): now basic.klass in ICLASS refers the
  old original class/module. [ruby-dev:45868][Bug #6662]
• class.c (rb_mod_ancestors): ditto.
• vm_method.c (search_method): search method entry from the origin
  iclass.
