In O3 model, MemBarrier instructions are inserted into the instruction queue by the InstructionQueue::insertBarrier (at src/cpu/o3/iew_impl.hh:1083). Barrier instructions are implicitly assumed to be non-speculative. Adding NonSpeculative flag to fence instruction makes it inserted into the instruction queue twice (at src/cpu/o3/iew_impl.hh:1083 and :1111). This can lead to a deadlock if both pointers to the instruction are not cleared from the queue when the instruction retires. This patch removes NonSpeculative flag from the fence inst.
