Don't serialize IC opcodes (#334)
Translate IC opcodes to their non-IC variants before writing them out. Before this commit they were not byte-swapped properly, breaking the ability to load serialized bytecode containing ICs on systems with different endianness. Inline caches are recomputed as needed now. A pleasing side effect of this change is that serialized bytecode is, on average, a little smaller because fewer atoms are duplicated now.
