LLVM alternativ

## Example

```rust

use std::error::Error;

use rllvm::prelude::*;

fn main() -> Result<(), Box>{

    let mut contxt = Context::new( Triple::host() )?;

    let func = contxt.add_function("add", vec![Type::u32, Type::u32], Type::u32);

    let asm = func.asm_func()?;

    let x = asm.arg(0).unwrap();

    let y = asm.arg(1).unwrap();

    func.ir.push( Return::new(*(x + y) ) );

    unsafe {

        let mut func: JitFunction u32> = contxt.get_jit_function("add")?;

        let out = func.call(5, 5);

        println!("main() -> {}", out);

    }

    Ok(())

}

```

## ToDo

Here is a bit of ToDo for my libary:

## v0.1.2

- [x] Starting high level ir struct

  - [x] Use traits `impl Compiler for Ir::Add` so i can overload the enum variants

  - [x] Make it compilable

  - [ ] Implement `mov`, `add`, `sub`, `mul`, `div` | `ints`, `floats`

    - [ ] mov

    - [x] add

    - [x] sub

    - [x] mul

    - [ ] div

    - [x] ints

    - [ ] floats

  - [x] Starting high level ir builder

    - [x] via traits

## v0.1.3

- [x] Implement `args` to the high level ir

- [x] Add option (in `context`) to compile to object file

- [ ] Naming convention

  - [x] generate

  - [ ] parse
