TimingSimpleCPU, which use atomic and timing memory accesses
respectively. Common code is factored into the BaseSimpleCPU class.
AtomicSimpleCPU includes an option (simulate_stalls) to add delays
based on the estimated latency reported by the atomic accesses.
Plain old "SimpleCPU" is gone; I have not updated all the config
files (just test/test.py).
Also fixes to get timing accesses working in new memory model and
to get split-phase memory instruction definitions working with
new memory model as well.
arch/alpha/isa/main.isa:
Need to include packet_impl.h for functions that use Packet objects.
arch/alpha/isa/mem.isa:
Change completeAcc() methods to take Packet object pointers.
Also split out StoreCond template for completeAcc(), since
that's the only one that needs write_result and we get an
unused variable warning if we always have it in there.

Special Regs (Hi,Lo,FCSR) are now added to the operands for use in decoder.isa.

cpu/ozone/cpu.hh:
Fixes for store conditionals. Use an additional lock addr list to make sure that the access is valid. I don't know if this is fully necessary, but it gives me a peace of mind (at some performance cost).
Make sure to schedule for cycles(1) and not just 1 cycle in the future as tick = 1ps.
Also support the new Checker.
cpu/ozone/cpu_builder.cc:
Add parameter for maxOutstandingMemOps so it can be set through the config.
Also add in the checker. Right now it's a BaseCPU simobject, but that may change in the future.
cpu/ozone/cpu_impl.hh:
Add support for the checker. For now there's a dynamic cast to convert the simobject passed back from the builder to the proper Checker type. It's ugly, but only happens at startup, and is probably a justified use of dynamic cast.
Support switching out/taking over from other CPUs.
Correct indexing problem for float registers.
cpu/ozone/dyn_inst.hh:
Add ability for instructions to wait on memory instructions in addition to source register instructions. This is needed for memory dependence predictors and memory barriers.

Intended Use:
A SimObject will call the serializer when it needs the state to be serializable (i.e. switchCPUs, checkpoint, switch memory access model). It will call the requestSeialization() function.
The Serializer will signal all the objects in its list to drain their state via the SimObject method drain(). Drain() has a default implementation to just signal done.
When each object is drained it will signal the Serializer that it has drained via the signalDrained() function.
The Serializer will collect these signals, when all have drained it will signal the initial requestor via serializationComplete() method in the SimObject.
Once that object is done, it will signal the Serializer to resumeExecution().
The Serializer will signal all the objects in its list to resume via the resume() method on the SimObject.
SConscript:
Add serializer object to build list
sim/sim_object.cc:
Add default behavior for drain (just signal finished, must be overided if you really must drain something)
