  -----------
  [LV] Separate AnyOf recurrence from getRecurrenceIdentity [NFC]

These recurrence types don't have a meaningful identity, and the
routine was abused to return the start value instead.  Out of the
three callers to this routine, only one actually wants this
behavior.  This is a prep change for removing the routine entirely
and commoning it with other copies of the same logic.
