I took the code from #290 (by @mxm and me) as the basis, but heavily
reworked it. Some code is similar most notably, the collapsed
address/release/bound check in the HybridMemorySegment. Most is different:
- The heap and off-heap code share more functions
- The off-heap segment is now a hybrid segment that can handle heap and
off-heap seamlessly.
- Strategy to load only one memory segment implementation (best JIT
efficiency)
- Improved and fixed bulk operations
- Many many many more tests
- Many bugs fixed on the way
- Added a suite of benchmarks to the tests
