loop.c (check_final_value): Use v->always_executed instead of v->always_computable.
* loop.c (check_final_value): Use v->always_executed
instead of v->always_computable.
* unroll.c (final_giv_value): Don't calculate the final
value as a function of the biv if the giv is not computed
for every loop iteration.
