Wojciech Matyjewicz 7b5b76835a Fix PR2002. Suppose n is the initial value for the induction ...

variable (with step 1) and m is its final value. Then, the correct trip 
count is SMAX(m,n)-n. Previously, we used SMAX(0,m-n), but m-n may 
overflow and can't in general be interpreted as signed.

Patch by Nick Lewycky.
