      Implement closures · ddabda9a
      Kevin Modzelewski authored
      Implementation is pretty straightforward for now:
      - find all names that get accessed from a nested function
      - if any, create a closure object at function entry
      - any time we set a name accessed from a nested function,
        update its value in the closure
      - when evaluating a functiondef that needs a closure, attach
        the created closure to the created function object.
      
      Closures are currently passed as an extra argument before any
      python-level args, which I'm not convinced is the right strategy.
      It's works out fine but it feels messy to say that functions
      can have different C-level calling conventions.
      It felt worse to include the closure as part of the python-level arg
      passing.
      Maybe it should be passed after all the other arguments?
      
      Closures are currently just simple objects, on which we set and get
      Python-level attributes.  The performance (which I haven't tested)
      relies on attribute access being made fast through the hidden-class
      inline caches.
      
      There are a number of ways that this could be improved:
      - be smarter about when we create the closure object, or when we
        update it.
      - not create empty pass-through closures
      - give the closures a pre-defined shape, since we know at irgen-time
        what names can get set.  could probably avoid the inline cache
        machinery and also have better code.
