As a result of 7192128, we extended the fix for 6948537 to G1's BlockOffsetTable, including adding a warning if the user overrode the default value.

Therefore we have code to emit such a warning in ConcurrentMarkSweepGeneration.cpp and G1CollectedHeap.cpp. It would be desireable to place the code that emits into a more centralized location, perhaps arguments.cpp.

EVALUATION Move warning code from concurrentMarkSweepGeneration.cpp and g1CollectedHeap.cpp to a more central location.
