- Support is provided by the Z module of the zarith package - when writing a literal number, you can add a suffix to tell the compiler what size it will use. no suffix means 32bits - add int type parameterized by bit length : i32, i64, i128, i69420... (no restriction for now as llvm is able to deal with it) idealy, for literals, there should be a type inference so we don't need to specify a suffix when dealing with type different than i32 but for now you must provide it. - check for out_of_bounds literal - int literals can have '_' separators : 1_000_000 is now valid

This aims at removing some boilerplate code by bringing mostly dependency-free PPX rewriters, maybe create one for our needs as well. As they are an AST to AST transformation, we can pretty-print it back to a PPX-free code to feed it to coq-of-ocaml for the long-term goal of proving the compiler using Coq.
Interesting PPXes :
