Fix OOM test case to handle more optimizations
The 080-oom-throw test case has some code in triggerInstanceOOM to
exhaust memory. Unfortunately, a sufficiently intelligent compiler can
inline the call to memEater.confuseCompilerOptimization and realize that
it is a no-op. In that case, the memEater variable is dead, and if a
compiler can improve the GC map, the only live heap data will be the
last allocated chunk.
Fix this by ensuring that the start of the chain (memEater) is really
live. Also ensure that it becomes dead before exiting the method, or the
subsequent println will fail allocating memory.
