Add explicit run configurations to java.lang.reflect and .runtime micros, aiming to reduce runtime while maintaining a decently high confidence that there's enough warmup to produce good enough data.
Roughly halves runtime of running `java.lang.reflect|java.lang.runtime` from 159 to 78 minutes. ------------- Commit messages: - Reduce runtime in java.lang.reflect/runtime microbenchmarks Changes: https://git.openjdk.java.net/jdk/pull/9013/files Webrev: https://webrevs.openjdk.java.net/?repo=jdk&pr=9013&range=00 Issue: https://bugs.openjdk.java.net/browse/JDK-8287798 Stats: 27 lines in 4 files changed: 25 ins; 2 del; 0 mod Patch: https://git.openjdk.java.net/jdk/pull/9013.diff Fetch: git fetch https://git.openjdk.java.net/jdk pull/9013/head:pull/9013 PR: https://git.openjdk.java.net/jdk/pull/9013
