Still to do: minimize changes in SimpleCPU code between full-system

full-system stuff moved into SimpleCPU should be put in a new System

Converted last remaining modules from C to C++ (mostly in /old).

original functions into two common template functions.
To support this, also renamed (read|write)[1248] on memory_object and
derivatives to just read & write, again overloaded on the type of the
'data' argument. Many of these functions could now be condensed into
a few template functions (though with a level of indirection so that
the interface can remain virtual). I did not do that though.

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!
src/arch/sparc/isa/decoder.isa:
Remove tons of MISCREG_XXXX defines that weren't used and ControlRegs in that were never used. Ones that were used rarely
changed to bitfields.
src/arch/sparc/isa/formats/integerop.isa:
These seems like a whole lot of overkill in printing, but i'll leave it the way it is for now. Allow Ccr to be set
at once
src/arch/sparc/isa/formats/priv.isa:
PrivTick is handled by miscreg now, don't need a seperate class for it
src/arch/sparc/isa/operands.isa:
prune the number of control regs down to a reasonable amount
src/arch/sparc/isa_traits.hh:
Replace 8 defines with 1 and flick some bits
src/arch/sparc/process.cc:
Better to clean the entire registers that specific bits which leads to indetermanistic behavior.
src/arch/sparc/regfile.hh:
Rip out storage that will never be backed by anything
Add storage for Priv and Hyperpriv registers
change defines to match the spec
change the way misc registers are named to match the spec with offsets to deal with ASR/PR/HPR/FSR.

src/arch/sparc/isa/formats/nop.isa:
Fix nop header so we can compile with multiple CPU models.
(Former code re-defined Nop object for each model.)
