Avoid overflow in step counter

This removes the `usize` argument to `inc_step_counter`. Now, the step
counter increments by exactly one for every terminator evaluated. After
`STEPS_UNTIL_DETECTOR_ENABLED` steps elapse, the detector is run every
`DETECTOR_SNAPSHOT_PERIOD` steps. The step counter is only kept modulo
this period.
