2016-04-18	make sure non-register temporaries get a slot	Quentin Carbonneaux
	Inside the main instruction-processing loop, it is taken care of by limit. However at block boundaries we are doing fancy bitset operations without calling limit.

2016-04-01	tradeoff the type of bsiter()	Quentin Carbonneaux
	int is used all over the place for temporaries, maybe this should be changed, I don't know. Another thing to consider is that temporaries are currently on 12 bits (and will be on 29 or 30 bits in the future), so int will always be safe to store them. We just loose the free invariant of non-negativity.
