RFR: 8016276: CMS concurrentMarkSweepGeneration contains lots of unnecessary allocation failure handling

[David Lindholm]

Hi,

Please review this fix that removes unnecessary error handling from 
concurrentMarkSweepGeneration.cpp. The error handling is performed in 
AllocateHeap(), which will exit the vm on malloc failure. The error 
handling in concurrentMarkSweepGeneration.cpp could never been reached.
