> 
> Rebase conflicts / fixes (so far):
>  * Rename `HeapRegion` -> `G1HeapRegion`
>  * Added SlidingForwarding to parallel full gc (See 3788dcbd02a5fb879ae91e3e5aa1aba8568362d5) 
>  * Disabled [JDK-8320448](https://bugs.openjdk.org/browse/JDK-8320448), will require adapting for CompactObjectHeaders (Created [JDK-8334971](https://bugs.openjdk.org/browse/JDK-8334971))
>  * Because UseObjectMonitorTable tags all allocations as `mtObjectMonitor` [JDK-8330849](https://bugs.openjdk.org/browse/JDK-8330849) will require some modification.
