Sanjoy Das 198959c487 Tighten the invariants around LoopBase::invalidate ...

Summary:
With this change:
 - Methods in LoopBase trip an assert if the receiver has been invalidated
 - LoopBase::clear frees up the memory held the LoopBase instance

This change also shuffles things around as necessary to work with this stricter invariant.
