Prevent concurrent GC stack-walks during deoptimization
We could end up modifying the instrumentation stack at the same time
the GC or thread-flip stack walks are occurring. This could cause
crashes or check-failures as the stack is in an inconsistent state.
To fix this we changed the deoptimization process to block GC stack
walks.
We also standardized openjdkjvmti.so deoptimization to use a single
entrypoint.
