Description
Create an "overview benchmark", consider different categories

- Single operation "mapping" - are all operations implemented? - could also be a separate benchmark, or extend existing ones.

- Reductions -> there is already VectorReduction2.java
- Read at offset, Aliasing Check
- MemorySegment, maybe Buffer (native memory)
- If-conversion (diamond, search loop, conditional store)
- Hand-unrolling
