Initial light-weight OoO CPU checkin, along with gcc-3.4 fixes.

SConscript:
    Include new files.
arch/alpha/isa_desc:
    Make the eaCompPtr and memAccPtr non-const so that execute() can be called on them.
arch/alpha/isa_traits.hh:
    Add enum for total number of data registers.
arch/isa_parser.py:
base/traceflags.py:
    Include new light-weight OoO CPU model.
cpu/base_dyn_inst.cc:
cpu/base_dyn_inst.hh:
    Changes to abstract more away from the base dyn inst class.
cpu/beta_cpu/2bit_local_pred.cc:
cpu/beta_cpu/2bit_local_pred.hh:
cpu/beta_cpu/tournament_pred.cc:
cpu/beta_cpu/tournament_pred.hh:
    Remove redundant SatCounter class.
cpu/beta_cpu/alpha_dyn_inst.cc:
cpu/beta_cpu/alpha_full_cpu.cc:
cpu/beta_cpu/alpha_full_cpu.hh:
cpu/beta_cpu/bpred_unit.cc:
cpu/beta_cpu/inst_queue.cc:
cpu/beta_cpu/mem_dep_unit.cc:
cpu/beta_cpu/ras.cc:
cpu/beta_cpu/rename_map.cc:
cpu/beta_cpu/rename_map.hh:
cpu/beta_cpu/rob.cc:
    Fix for gcc-3.4
cpu/beta_cpu/alpha_dyn_inst.hh:
cpu/beta_cpu/alpha_dyn_inst_impl.hh:
    Fixes for gcc-3.4.
    Include more variables and functions that are specific to AlphaDynInst which were once in BaseDynInst.
cpu/beta_cpu/alpha_full_cpu_builder.cc:
    Make params match the current params inherited from BaseCPU.
cpu/beta_cpu/alpha_full_cpu_impl.hh:
    Fixes for gcc-3.4
cpu/beta_cpu/full_cpu.cc:
    Use new params pointer in BaseCPU.
    Fix for gcc-3.4.
cpu/beta_cpu/full_cpu.hh:
    Use new params class from BaseCPU.
cpu/beta_cpu/iew_impl.hh:
    Remove unused function.
cpu/simple_cpu/simple_cpu.cc:
    Remove unused global variable.
cpu/static_inst.hh:
    Include OoODynInst for new lightweight OoO CPU
