RFR: 8312420: Integrate Graal's blender micro benchmark

[Joshua Cao]

We would like to integrate Graal's blender micro benchmark from https://www.graalvm.org/22.1/examples/java-performance-examples/. We have been using this benchmark to test our partial escape analysis work (https://mail.openjdk.org/pipermail/hotspot-compiler-dev/2023-July/066670.html). This test can exist independently of the project.


example command to run test:


make run-test TEST=micro:org.openjdk.bench.vm.compiler.pea.Blender MICRO="FORK=1;OPTIONS=-prof gc -gc true"


example output (not complete):
