Subject: Free iv index table

IV index tables weren't being freed.  This program would leak memory:

```ruby
loop do
  k = Class.new do
    def initialize
      @a = 1
      @b = 1
      @c = 1
      @d = 1
      @e = 1
      @f = 1
      @g = 1
    end
  end
  k.new
end
```

This commit fixes the leak.
