Update Virtual and Physical ports.

src/cpu/o3/alpha/cpu_impl.hh:
    Handle the PhysicalPort and VirtualPort in the ThreadState.
src/cpu/o3/cpu.cc:
    Initialize the thread context.
src/cpu/o3/thread_context.hh:
    Add new function to initialize thread context.
src/cpu/o3/thread_context_impl.hh:
    Use code now put into function.
src/cpu/simple_thread.cc:
    Move code to ThreadState and use the new helper function.
src/cpu/simple_thread.hh:
    Remove init() in this derived class; use init() from ThreadState base class.
src/cpu/thread_state.cc:
    Move setting up of Physical and Virtual ports here.  Change getMemFuncPort() to connectToMemFunc(), which connects a port to a functional port of the memory object below the CPU.
src/cpu/thread_state.hh:
    Update functions.
