Subject: [PATCH] Serialization changes to make O3CPU consistent with the other
 models.

src/cpu/o3/commit_impl.hh:
    Always set instruction.  This is necessary for serialization as the instruction is also serialized.
src/cpu/o3/cpu.cc:
    Change serialization so it matches other CPU's output.  Also fix up some indexing.
