Bug #21103: Binding problem with delegate methods

----------------------------------------
```ruby
def foo(...)
  a = 123
  binding.local_variable_get(:a)
end

p foo([])
```

Expected output is `123`, actual output is some number.  I think there is an off-by-one error in bindings created from delegate frames.
