minor change to syntax of 'def operands' in ISA descriptions.
arch/alpha/isa/main.isa:
arch/mips/isa/operands.isa:
arch/sparc/isa/operands.isa:
Change 'def operands' statement to work with new
isa_parser changes.
arch/isa_parser.py:
Merge OperandTraits and OperandDescriptor objects into a
unified hierarchy of Operand objects.
Required a change in the syntax of the 'def operands'
statement in the ISA description.

=================================================
-every MIPS32 ISA is represented with some type
of code block.
-any instruction that doesnt have a code block
would be of format WarnUnimpl. Examples of the
ones I am waiting on further info to implement
are the TLB register insts, memory consistency
instructions (ll,sc,etc.) and software debug
insts.

arch/mips/isa/decoder.isa:
Code for di,ei,seb,seh,clz,and clo ....
Every instruction has a format now (of course these are initial formats are still subject to change!)
arch/mips/isa/formats/branch.isa:
Format Branch in MIPS similar to Alpha Format

SConscript:
Moved some files out of targetarch. The either no longer need to be there, never needed to be there, or should be referred to directly in arch/alpha due to there strictly alpha content.
arch/alpha/isa_traits.hh:
Added alpha's endianness to it's isa_traits.hh
arch/mips/isa_traits.hh:
Added MIPS endianness to it's isa_traits.hh
arch/sparc/isa_traits.hh:
Added SPARCs endianess to it's isa_traits.hh
build/SConstruct:
Added MIPS as a valid architecture
cpu/exec_context.hh:
Included arch/isa_traits.hh to bring in the endianness of the system.
cpu/o3/alpha_cpu.hh:
Included arch/isa_traits.hh to bring in the systems endianness, and removed the hardcoding of little endianness
cpu/o3/fetch_impl.hh:
kern/freebsd/freebsd_system.cc:
Included arch/isa_traits.hh to bring in the systems endianness, and removed the hardcoding to little endianness.
sim/system.cc:
Included arch/isa_traits.hh to bring in the systems endianness, and removed the hardcoding to little endian.

The extra class is needed because of the necessisty of an immediate member variable.
Also, added some 'very modest' python code to choose between the IntOp and
the IntImmOp based on the instruction name ...

arch/mips/isa/formats/int.format:
Looks like Integer Ops with Immediates may not need their own separate class because all those instructions are distinct from
their reg-reg counterparts

All of the code literals are empty as of now. As much as possible instructions were organized into relevant "formats"
and also references to the tables I used from the MIPS manual were noted via appropriate comments.

- this will decode the instructions but not doing anything to create the C++ object yet
(the 1st of many steps!)
arch/mips/isa_desc/bitfields.h:
initial bitfield constants ... copied some from original alpha bitfields
arch/mips/isa_desc/decoder.h:
decoder function skeleton pt.1
- this will decode the instructions but not doing anything to create the C++ object yet
(the 1st of many steps!)
