Kevin Lim 248bd2bb62 Various branch predictor fixes/cleanup. It works more correctly now and supports both local and tournament predictors.
cpu/o3/2bit_local_pred.cc:
    Branch predictor cleanup/fixup.  Rename this to LocalBP.
cpu/o3/2bit_local_pred.hh:
    Rename to LocalBP, update to support changes to BPredUnit, include comments.
cpu/o3/alpha_cpu_builder.cc:
    Support extra parameters to the branch predictor.  Now it takes in a parameter to tell it which branch predictor it is using, the local or the tournament predictor.
cpu/o3/alpha_params.hh:
    Add in extra parameter for the branch predictor type.
cpu/o3/bpred_unit.cc:
    Branch predictor fixup/cleanup.  Rename it to BPredUnit.
cpu/o3/bpred_unit.hh:
    Branch predictor fixup/cleanup.  Now supports both the local and tournament predictors, and stores the branch predictor update state.
cpu/o3/bpred_unit_impl.hh:
    Branch predictor overhaul.  Now supports both the local and tournament predictors.
cpu/o3/cpu_policy.hh:
cpu/ozone/ozone_impl.hh:
cpu/ozone/simple_impl.hh:
    Reflect the class name change.
cpu/o3/decode_impl.hh:
    Be sure to set the predicted target as well so we don't squash twice.
cpu/o3/tournament_pred.cc:
cpu/o3/tournament_pred.hh:
    Fixes to the tournament predictor.
cpu/ozone/simple_params.hh:
    Include parameter for the branch predictor type.
python/m5/objects/AlphaFullCPU.py:
python/m5/objects/OzoneCPU.py:
    Include the parameter for the branch predictor type.
