We are trying to make a wrapper of MLIR for Julia in https://github.com/JuliaLabs/MLIR.jl, but some dialects are missing in `libMLIR-C`. This PR adds them.
Toy Tutorial
This contains sample code to support the tutorial on using MLIR for building a compiler for a simple Toy language.
See docs/Tutorials/Toy at the root of the project for more informations.
