Thomas Wuerthinger a53aa2e6fd Initial version for thomaswue with Oracle GraalVM Native Image ...

* Initial version.

* Make PGO feature optional off-by-default. Needs PGO_MODE environment
variable to be set. Add -O3 -march=native tuning flags for better
performance.

* Adjust script to be more quiet.

* Adjust max city length. Fix an issue when accumulating results.

* Tune thomaswue submission.
mmap the entire file, use Unsafe directly instead of ByteBuffer, avoid byte[] copies.
These tricks give a ~30% speedup, over an already fast implementation.

* Optimize parsing of numbers based on specific given constraints.

* Fix for segment calculation for case of very small input.

* Minor shell script fixes.

* Separate out build step into file additional_build_step_thomaswue.sh,
simplify run script and remove PGO option for now.

* Minor corrections to the run script.
