Description
The G1 collector maintains TaskQueues and associated overflow stacks in instances of G1ParScanThreadState, and has custom code to collect statistics on TaskQueue operations. These should be changed to use OverflowTaskQueue, which has built-in overflow handling and statistics, to reduce code duplication.
