# TODO: The bytecode compiler that was used in Bishi seems to like using
# registers as temporary storage for variables in a lot of cases. We should
# be able to track register assignment and use and see if there is only one
# use/assignment of a register after all other optimization passes are done.
# If this is the case, we should be able to substitute the original assignment
# for the register when used, and get rid of the assignment altogether. This
# should slightly clean up a fair bit of code.
