New codegen! Rewritten codegen to use the llvm bindings Everything except struct are back to normal, and there a a few additions. 1. Correct code in more cases, return at the end of a while/if wont generate a "ret" followed by a "br". 2. Better scope, "int x = x" now illegal 3. Probably more

int main()
{
    int x = 1 + 2 * 3 + 4 + 5;
    int y = x - x;
    return y + x - 15;
}
