Description

The root issue for JNI improvements:

Clean:
HARMONY-4705 [drlvm][jni] JNI transition uses ineffective TLS get
HARMONY-4811 [drlvm][exception] exn_raised() should cache the TLS

Dirty:
HARMONY-4714 [drlvm][jni] JNI transition checks exceptions twice

Proof-of-concept
HARMONY-4729 [drlvm][jni] JNI transition should inline hythread_suspend_enable() and hythread_suspend_disable()
HARMONY-4806 [drlvm][jni] Experiment: rewriting entire JNI transition stub on encoder
