Add mechanism for recycling temp slots.

Previously, every time we used a value slot for something ephemeral
(e.g. a continue-mask in a loop), the slot was lost forever. Now,
it is added to a recycle-list and can be reclaimed.

I think I will need a temporary value slot to implement non-constant
array indexing, and it would be pretty wasteful if every array index
burned a slot forever.
