Synchronize JNI critical calls with the CC collector thread flip.
JNI critical calls (like GetArrayElementsCritical) would need to block
for the whole GC run to finish if the CC collector GC is ongoing. This
CL changes it so that they don't need to block for the GC run, but
only for the duration of the thread flip operation, which is much
shorter. This is valid due to the to-space invariant.
