Fix recurrence rule expansion with ordered weekday
When the order of a weekday in BYDAY rule expansion (like -5SA or 5SU
for monthly or 55WE for yearly) exceeds the number of available weekdays
in the period (month or year), rule expansion with negative order could
result in a floating point exception. The reason: the modified frequency
might become zero.
Solution. Check order against number of available weekdays and terminate
expansion early whenever possible (also for positive orders).
