As a developer, I should be able to run Maki's test suite automatically, so that I can quickly check my changes for bugs

Maki's test suite must currently be run manually; however it would be nice if it could be run automatically instead.
I've set up automated test suites for Clang-based projects before using llvm-lit, so I could set up such a lit here and then we would just need to annotate Maki's test cases with their expected output.

Automating Maki's test suite would be a significant improvement since it would make it far faster to test the project.
The only obstacles are setting up the boilerplate llvm-lit code and annotating the existing test cases.
