Rip out storage in miscreg file that will never store anything
Add storage and defines for Priv and Hyperpriv registers
Change defines to match the spec register numbers
Change the way misc registers are named to match the spec with offsets to deal with ASR/PR/HPR/FSR.
Change contextval to an int since both global registers and windowed registers are indexed by int in UA2005.
Use bitfields for things that are rarely used in decoder
Instead of decoding ASR/PR/HPR and having a specfic instruction, use a generic instruction instead
Still todo:
Protect rdpr, rdhpr, wrpr, wrhpr with checks that fault in insufficient privs
Deal with signaling interrupts on timer expiration
Deal with writes to softint/PIL generating interrupts how those are vectored to the CPU
Other misc:
Instruction decoding needs major help!

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.

files (just test/test.py).

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)
