All the low-level stepping is done in the infrun.c file. Look
particularly at the handle_inferior_event function which is called for
each target stop event. There you'll find calls to bpstat_stop_status
(defined in breakpoint.c) where watchpoint expressions are re-evealuated
and compared to their old value.
