Added IrTypeFunction and IrTypeDelegate and eliminated IrDType. This means the Type::ir field can be removed. It's the final part needed for the move to a slightly more sane type system. Now the whole thing just needs to be cleaned up :P Added -v-cg switch, which right now just prints "codegen: module.name (module/name.d)" to stdout, this can really help figuring out where, in some complex build command, things go wrong.

module unrolled;

extern(C) int printf(char*, ...);

void test(T...)(T t) {
    foreach (value; t) {
        printf("%d\n", value);
        if (value == 2)
            break;
    }
}

void main() {
    test(1,4,3);
}
