1. Remove redundant instructions.
2. Create a mapping of jumps and branches to target labels.
3. Assemble to a preliminary bytecode. Jumps and branches do not have an address at this point. Jumps are a single
byte long at this point. The opcode used by jumps is "jump32".
4. Attempt to shrink the size of the jump and branch instructions. Use "jump16" or "jump8" if possible. Likely the
very definition of "premature optimization", but I like it.
