gem5/cpu/o3/alpha_cpu_builder.cc
Kevin Lim a8b03e4d01 Updates for O3 model. 
arch/alpha/isa/decoder.isa:
    Make IPR accessing instructions serializing so they are not issued incorrectly in the O3 model.
arch/alpha/isa/pal.isa:
    Allow IPR instructions to have flags.
base/traceflags.py:
    Include new trace flags from the two new CPU models.
cpu/SConscript:
    Create the templates for the split mem accessor methods.  Also include the new files from the new models (the Ozone model will be checked in next).
cpu/base_dyn_inst.cc:
cpu/base_dyn_inst.hh:
    Update to the BaseDynInst for the new models.
