827c4e172a Cuts a third from the Program struct. 
Observation: [source/destination]_address are always one of the address registers. So you can fit both within a single byte.

Net effect: around a 12% reduction in execution costs, given that this reduces the size of the instructions table from 3mb to 2mb.
