Vector API micro benchmarks are currently located under test/jdk/jdk/incubator/vector/benchmark which makes them rather as "dead" code without possibility to built and run.

The proper location for micro benchmarks is actually test/micro/ directory.
It would be nice to move Vector API benchmarks there so they can be built automatically as part 'test-image' make target.
Once they are built they can be run as
 make run-test TEST=micro:BENCHMARK_TEST_NAME
