1MB increase in binary size

Binary size increased by ~50% from [v0.5](https://github.com/LightAndLight/ipso/releases/tag/v0.5) to [v0.6](https://github.com/LightAndLight/ipso/releases/tag/v0.6). I added a bunch of builtins in 0.6, but should it result in a megabyte's worth of CPU instructions? Investigate.
