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 bug50;
extern(C) int printf(char*, ...);

struct S
{
    int i;
    float f;
    long l;

    void print()
    {
        printf("%d %f %lx\n", i, f, l);
    }
}

void main()
{
    S s;
    s.print();
    s = S(1,2,3);
    s.print();

    S[] arr;
    {arr ~= s;}
    {arr[0].print();}
    {arr ~= S(1,2,3);}
    {arr[1].print();}
}
