Revert^2 "Correctly handle thread deopt with thread-specific JVMTI events"
This reverts commit b2a8964f4218c2c52dacf599ebf5cf69f8753bf0.
It turns out that transitioning from instrumentation trampolines and
interpreter trampolines interacts in a racy way with single thread
deoptimization. This caused tests that perform this transition
repeatedly to be flaky when run with the --trace. Since it is expected
to be rare that one traces at the same time they are performing JVMTI
functions (since JVMTI is a superset of trace behaviors) we solved
this by simply not allowing the transition.
Reason for revert: Prevented unsafe transition between entry-exit
trampolines and interpreter only.
