Factor out the common subexpression month_remainder * DAYS_PER_MONTH
in interval_mul and interval_div.  This avoids an optimization bug
in A Certain Company's compiler (and given their explanation, I wouldn't
be surprised if other compilers blow it too).  Besides the code seems
more clear this way --- in the original formulation, you had to mentally
recognize the common subexpression in order to understand what was going
on.
