RFR: 8179064: TestInterpreterMethodEntries.java is missing -XX:+UnlockDiagnosticVMOptions

[Erik Helin]

Hi all,

this small patch adds the flag -XX:+UnlockDiagnosticVMOptions when 
TestInterpreterMethodEntries.java is using -XX:+UseCRC32Intrinsics. 
-XX:+UseCRC32Intrinsics is an diagnostic flag, so the test fails if 
-XX:+UnlockDiagnosticVMOptions isn't set.

Testing:
- JPRT
- make run-test 
TEST=hotspot/test/runtime/SharedArchiveFile/TestInterpreterMethodEntries.java

Thanks,
Erik
