 I've done some looking, and I haven't found a case where C's arithmetic
 types aren't implemented as integers or words. Furthermore, the arithmetic
 types already allow (*) via Num, so it'd be nice to have them be Integral
 types so that we have div, too.

 I propose we include Bits, Enum, and Integral instances for CTime and
 friends.
