There are few bugs in SetBreakpoint when it reaches for metaspace allocation, notably [JDK-8214992](https://bugs.openjdk.java.net/browse/JDK-8214992) and [JDK-8264149](https://bugs.openjdk.java.net/browse/JDK-8264149). This adds the test that exercises the metaspace allocation paths.
Additional testing: - [x] New test on Linux x86_64 fastdebug - [x] New test on Linux x86_64 release - [x] New test with [JDK-8264149](https://bugs.openjdk.java.net/browse/JDK-8264149) reverted fails on Linux x86_64 release ------------- Commit messages: - Fix Changes: https://git.openjdk.java.net/jdk/pull/7554/files Webrev: https://webrevs.openjdk.java.net/?repo=jdk&pr=7554&range=00 Issue: https://bugs.openjdk.java.net/browse/JDK-8282170 Stats: 1127 lines in 2 files changed: 1127 ins; 0 del; 0 mod Patch: https://git.openjdk.java.net/jdk/pull/7554.diff Fetch: git fetch https://git.openjdk.java.net/jdk pull/7554/head:pull/7554 PR: https://git.openjdk.java.net/jdk/pull/7554
