Comment(by mwiebe):

 I made it bytes to reduce the amount of memory which may need to be read
 from main memory into the cache during type promotion. The can_cast and
 type_promotion tables contain 24*24=576 entries. That's 576 bytes using
 signed char vs 2304 bytes using int. I'd prefer to keep it bytes unless
 some benchmarks show a performance benefit for int.
