rev 4495 : 8012715: Fix G1 bug in graphKit.cpp: Access of PtrQueue::_index was int not size_t. 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.28 lines changed: 4 ins; 12 del; 12 mod; 3829 unchg
