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 tangotests.aa1_1;

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

void main()
{
    int[int] map;
    map[1] = 1;
    map[10] = 1;
    map[11] = 11;
    map[14] = 41;
    map[21] = 12;
    map[23] = 32;
    map[32] = 23;
    map[201] = 102;
    foreach(k,v; map)
    {
        printf("%d:%d ", k,v);
    }
    printf("\n");
}
