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.

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

class C
{
    int i;
    void p()
    {
        printf("%d\n", i);
    }
}

void main()
{
    printf("should print 4\n");
    C c = new C;
    c.i = 4;
    c.p();
    //delete c;
}
