Matt Matejczyk 01ccd2e19e Optimize GetControllerOf method 
In addition create a similar method that doesn't copy objects.

Benchmark for the new no-copy method vs the old one:
```
benchmark                       old ns/op     new ns/op     delta
BenchmarkGetControllerOf-12     214           14.8          -93.08%

benchmark                       old allocs     new allocs     delta
BenchmarkGetControllerOf-12     1              0              -100.00%

benchmark                       old bytes     new bytes     delta
BenchmarkGetControllerOf-12     80            0             -100.00%
```

Benchamrk for the new (copy) method vs the old one:
```
benchmark                       old ns/op     new ns/op     delta
BenchmarkGetControllerOf-12     128           114           -10.94%

benchmark                       old allocs     new allocs     delta
BenchmarkGetControllerOf-12     1              1              +0.00%

benchmark                       old bytes     new bytes     delta
BenchmarkGetControllerOf-12     80            80            +0.00%

```

Overall there is a 10% improvement for the old vs new (copy) method and
huge improvent (x10) for the old vs new (no-copy).

I changed the IsControlledBy and a few other methods to use the new (no-copy) method.
