* insns.def (getinlinecache/setinlinecache): compare ic->ic_cref and

  current cref only when cached CREF list includes singleton class.

  Singleton classes have own namespaces, so that we need to check
  cref as a key (#10943).

  However, if current CREF list does not include singleton class,
  no need to check CREF beacuse it should be same name space.

* vm_insnhelper.c (vm_get_const_key_cref): add a function returns
  CREF only when it includes singleton class.

* vm_core.h: constify iseq_inline_cache_entry::ic_cref.
