Rearranged things so that classes with more than one execute function treat operands properly.
1. Eliminated the CodeBlock class
2. Created a SubOperandList
3. Redefined how InstObjParams is constructed
To define an InstObjParam, you can either pass in a single code literal which will be named "code", or you can pass in a dictionary of code snippets which will be substituted into the Templates. In order to get this to work, there is a new restriction that each template has only one function in it. These changes should only affect memory instructions which have regular and split execute functions.
Also changed the MiscRegs so that they use the instrunctions srcReg and destReg arrays.

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!
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.
change contextval to an int since both global registers and windowed registers are indexed by int in UA2005.

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.)
