      Description

      Add support for adaptive IHOP, recalculating that value every GC based on current heap size, allocation reserves, promotion rate and other metrics.

      Support should be gated behind a new switch called -XX:+G1UseAdaptiveIHOP. Basic tracing should be provided using -XX:+PrintAdaptiveSizePolicy.
