Fix so that O3CPU doesnt segfault on exit.

Major thing was to not execute commit if there are no active threads in CPU.

src/cpu/o3/alpha/thread_context.hh:
    call deallocate instead of deallocateContext
src/cpu/o3/commit_impl.hh:
    dont run commit stage if there are no instructions
src/cpu/o3/cpu.cc:
    add deallocate event, deactivateThread function, and edit deallocateContext.
src/cpu/o3/cpu.hh:
    add deallocate event and add optional delay to deallocateContext
src/cpu/o3/thread_context.hh:
    optional delay for deallocate
src/cpu/o3/thread_context_impl.hh:
    edit DPRINTFs to say Thread Context instead of Alpha TC
src/cpu/thread_context.hh:
    optional delay
src/sim/syscall_emul.hh:
    name stuff
