A common annoyance when using G1 is tuning of the IHOP value for both avoiding full gcs and also reaching optimal throughput.

Implement functionality to automatically set the current IHOP value so that full gc is very unlikely and throughput is optimized.

This is an umbrella CR for this set of changes.
