Fixed up the isa description. Also added some capability to the isa_parser in the InstObjParams constructor.

arch/isa_parser.py:
    Expanded the capability of the InstObjParams constructor to allow adding in extra keys for use in templates. These are added as key, value tuples as optional arguements.
arch/sparc/isa/base.isa:
arch/sparc/isa/formats/mem.isa:
arch/sparc/isa/formats/priv.isa:
    The genCompositeIop function is no longer needed, as this functionality is now in the InstObjParams constructor.
arch/sparc/isa/decoder.isa:
    Fixed up alot of instructions, and fixed indentation.
arch/sparc/isa/formats/integerop.isa:
    The genCompositeIop function is no longer needed, as this functionality is now in the InstObjParams constructor. Also changed the immediate values to be signed.
base/traceflags.py:
    Added SPARC traceflag
configs/test/hello_sparc:
    Recompiled without -mflat
cpu/cpu_exec_context.cc:
    Used the regfile clear function rather than memsetting to 0.
