* vm.c (rb_vm_cref_replace_with_duplicated_cref): added.

  CREFs should not be shared by methods between `using'.
  [Bug #11247]

* vm_insnhelper.c (vm_cref_replace_with_duplicated_cref): ditto.

* vm.c (vm_cref_dup): should copy refinements correctly.

* eval.c: use rb_vm_cref_replace_with_duplicated_cref().

* eval_intern.h: add a decl. of
  rb_vm_cref_replace_with_duplicated_cref().

* vm_eval.c (eval_string_with_cref): do not need to pass
  scope's CREF because VM can find out CREF from stack frames.

* test/ruby/test_refinement.rb: add a test.
