rev 4486 : 8012335: G1: Fix bug with compressed oops in template interpreter on x86 and sparc.
Summary: In do_oop_store the uncompressed value of the oop being stored needs to be preserved and passed to g1_write_barrier_post. This is necessary for the heap region cross check to work correctly.

rev 4475 : 8009536: G1: Apache Lucene hang during reference processing
Summary: In CMTask::do_marking_step(), Skip offering termination and entering the first and second synchronization barriers if called from a serial context, i.e. the VM thread.

rev 4481 : 8009940: G1: assert(_finger == _heap_end) failed, concurrentMark.cpp:809
Summary: Skip reference processing if the global marking stack overflows during remark. Refactor and rename set_phase(); move code that sets the concurrency level into its own routine. Do not call set_phase() from within parallel reference processing; use the concurrency level routine instead. The marking state should only set reset by CMTask[0] during the concurrent phase of the marking cycle; if an overflow occurs at any stage during the remark, the marking state will be reset after reference processing.

rev 4482 : 8008301: G1: guarantee(satb_mq_set.completed_buffers_num() == 0) failure
Summary: If the marking stack overflows while the marking tasks are draining the SATB buffers, remark will exit with some SATB buffers left unprocessed. Relax the guarantee to allow for overflow.

rev 4487 : 8012715: G1: GraphKit accesses PtrQueue::_index as int but is size_t
Summary: In graphKit INT operations were generated to access PtrQueue::_index which has type size_t. This is 64 bit on 64-bit machines. No problems occur on little endian machines as long as the index fits into 32 bit, but on big endian machines the upper part is read, which is zero. This leads to unnecessary branches to the slow path in the runtime.
