First release tracking issue

[RDambrosio016]

Small issue to track the things that need to be done before the project will be released.

• Get CGUs to work, needs work on the codegen to merge llvm ir modules, probably not too hard.
• Add a couple more basic examples.
• Update nightly close to release.
• Merge First pass #1
• Make i128 work, shouldn't be too hard, just removing special casing for it since we already handle irregular ints just fine.
• [meta] Add proper labels and maybe templates
• Add the raytracer i posted to the examples
• Actually pass codegen args in cuda_builder
• Make the readme
• implement the ABI calculation logic, probably the hardest thing here
• Use prebuilt LLVM.
