day 18 part 2
64-bit math, yet again. Thank goodness I already had an O(n)
algorithm in place; the bear here was adjusting things to work with
math64.m4 in place (including the fact that both 'add64' and 'a1'
macros defined in that file can conflict with arbitrary hex numbers).
~375ms for GNU, ~400ms for POSIX (parsing time is still noticeable,
despite the dominant time being spent on the 64-bit math).
