[8u] RFR: 8173361: various crashes in JvmtiExport::post_compiled_method_load

Hi,

Please review the backport of JDK-8173361 to 8u.
Bug: https://bugs.openjdk.java.net/browse/JDK-8173361
11u commit: https://hg.openjdk.java.net/jdk-updates/jdk11u/rev/99bdef096320
8u webrev: https://cr.openjdk.java.net/~dongbohe/8173361/webrev.00/

This patch doesn't apply cleanly.
I turned NoSafepointVerifier to No_Safepoint_Verifier because JDK- 8146690[1] changed the naming convention.
I removed the mutexLocker.cpp changeset because JDK-8047290[2]  does not exist in 8.
I added the CLDClosure* to ServiceThread::oops_do because JDK- 8154580[3] does not exist in 8.

Tested with tier1. No regression in tests.
Follow-up fix JDK-8235218[4] is planned to be backported as well.
