8173361: various crashes in JvmtiExport::post_compiled_method_load

[kvergizova]

I'd like to backport 8173361 to 13u for parity with 11u.
The patch doesn't apply cleanly due to minor context differences in serviceThread.hpp and mutexLocker.cpp (JDK-8170299 and JDK-8231472 are not in 13u), reapplied manually.
Tested with tier1 and other jvmti tests.
Follow-up fix JDK-8235218 is planned to be backported as well.
