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.

class Foo
{
    this(int j)
    {
        i = pi = j;
    }

    int i;

private:

    int pi;
}

class Bar : Foo
{
    this(int j)
    {
        super(j);
        baz = 42;
    }

    int baz;
}

void func()
{
    auto bar = new Bar(12);
}

void main()
{
    func();
}
