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
