Fix instruction count computation ( #26 )
...
The instruction count is shown twice, with both numbers incorrect.
This PR fixes the first one.
The second one comes from the stats section which is off by one since it
counts "entry:", which is also why the Prevail "check" tool skips
printing it. I'm following up separately to see if that one can just be removed.
