      Don't pre-initialise block contexts with holes · 92e6f7a3
      rossberg authored
      Respective declarations will explicitly initialise slots
      with the hole anyway, so this always was unnecessary.
      With varblocks it even became wrong, because block contexts
      may now host var bindings, which want undefined.
      
      Fixes the hole leaking when accessing an unitialised,
      block-context-allocated var.
