[ruby-core:95192] [Ruby master Bug#15629] super_method fails on binded/unbinded/cloned methods

[merch-redmine@jeremyevans.net]

Issue #15629 has been updated by jeremyevans0 (Jeremy Evans).

File super_method-bind-unbind-clone-15629.patch added

This bug is due to the fact that bind/unbind/clone do not copy the `iclass` entry, and without an `iclass` entry, `super_method` returns `nil`.  Attached is a patch that fixes this issue.

Bug #15629: super_method fails on binded/unbinded/cloned methods

derived from #13973:

```
module A
  def foo
  end
end

module B
  def foo
  end
end

class C
  include A
  include B
end

c = C.new
m1 = c.method(:foo)
p m1.super_method         # => #<Method: A#foo>
p m1.clone.super_method   # => nil
p m1.unbind.super_method  # => nil

m2 = C.instance_method(:foo)
p m2.super_method         # => #<UnboundMethod: A#foo>
p m2.clone.super_method   # => nil
p m2.bind(c).super_method # => nil
```

`super_method` of binded/unbinded/cloned method should be `super_method` of original method, shouldn't it?
