[Truffle] Super passing wrong block

[nirvdrum]

The tests for hike have a failure because we're not passing the correct block to super. I've extracted a smaller snippet to demonstrate the problem:

class UppercaseArray < Array
  def collect!
    super do |element|
      result = yield element
      normalize_element(result)
    end
  end

  def normalize_element(element)
    element.upcase
  end
end

a = UppercaseArray.new
a.push "a", "b", "c"
a.collect! { |x| x.downcase }

p a

This should print ["A", "B", "C"], but instead prints ["a", "b", "c"].

The block from the collect! call (i.e., the one with x.downcase) is being passed to super and the block attached to the super call is completely ignored.

If there's not a RubySpec covering the behavior, we should look at adding one.

I think this is a variation of the same problem (this time take from mime-types):

class HashWithArrayDefault < Hash
  def initialize
    super { |h, k| h[k] = [] }
  end
end

h = HashWithArrayDefault.new

p h[:not_exists] == []

This should print true, but instead prints false.
