A couple of minor fixes.

A couple of minor fixes.
1. Set CPU ID in all modes for the O3 CPU.
2. Use nextCycle() function to prevent phase drift in O3 CPU.
3. Remove assertion in rename map that is no longer true.

src/cpu/o3/alpha/cpu_builder.cc:
    Allow for CPU id in all modes, not just full system.  Also include a parameter that was left out by accident.
src/cpu/o3/alpha/cpu_impl.hh:
    Set the CPU ID properly.
src/cpu/o3/cpu.cc:
src/cpu/o3/cpu.hh:
    Use nextCycle() function so that the CPU does not get out of phase when starting up from quiesces.
src/cpu/o3/rename_map.cc:
    Remove assertion that is no longer true.
tests/configs/o3-timing.py:
    Set CPU's id to 0.
