Fix Windows crash from stop_pc change

The "make thread_suspend_state::stop_pc optional" patch caused a
regression on Windows when using shared libraries.  I tracked this
down to an unguarded use of stop_pc() in the TARGET_WAITKIND_LOADED
case of handle_inferior_event.  This patch fixes the bug by ensuring
that the stop PC is set at this point.
