Bug #9452: Refining methods that should be private

Are refinements also meant to add private methods? This is what I tried:

module R
  refine Object do
    def m
      puts "Success!"
    end

    private(:m)
  end
end

using R

m # success
42.m # success (= not private)

However, I can get near the desired functionality by defining a private method first:

class Object
  private
  def m
  end
end

module R
  refine Object do
    def m
      puts "Success!"
    end
  end
end

using R
m # success
42.m # no success (= it is private)

It calls the right code. But requires global core ext.

• vm_insnhelper.c (vm_call_method): should check ci->me->flag of
  a refining method in case the method is private.
  [Bug #9452]

• vm_method.c (make_method_entry_refined): set me->flag of a refined
  method entry to NOEX_PUBLIC in case the original method is private
  and it is refined as a public method. The original flag is stored
  in me->def->body.orig_me, so it's OK to make a refined method
  entry public. [Bug #9452]
