[12] RFR 8215375: [Graal] jck:vm/jvmti/Exception/excp001/excp00101 fails in Graal as JIT mode and -Xcomp mode

[Doug Simon]

Please review this fix that makes Graal compiled code post a JVMTI event when throwing an exception.
The code to post the event is only compiled in if the relevant JVMTI capabilities are enabled at compile time. The event posting code performs a dynamic check to see if the current thread is interested in exception events before posting an event.

Testing: hs-tier6-graal
