I personally don't like alloca but figured that in this case we were
not allocating much memory (OK, I suppose there are pathological
functions with gazillions of loops).  I have no objections to changing
it.  Anyway, it's only an interim measure since my low-overhead
looping patches does away with the used_count_register field
altogether.
