Having to comb through them and change their `#pragma option -zC` names
after adding a new one is pretty annoying, after all. This way, we also
get to move some of those 2020 decompilations out of the `th05/`
subdirectory, matching the more consistent directory hierarchy that
this project has converged on in the years since.
