RFR 8166848: Performance bug: SystemDictionary - optimization

[serguei.spitsyn at oracle.com]

Hi Coleen,

It looks good to me.
Nice simplification!

One tip is to use the bucket_count for incrementing the element_count:
    element_count += bucket_count;

out of the internal for-loop.
It is to underline the relationship between the two counters.

Thanks,
Serguei
