updated MIPS ISA files .... all files should be able to compile/build with MIPS option except isa_traits.*
which I need to update the misc. regfile accesses

arch/mips/faults.cc:
arch/mips/faults.hh:
    alpha to mips
arch/mips/isa/base.isa:
    add includes
arch/mips/isa/bitfields.isa:
    more bitfields
arch/mips/isa/decoder.isa:
    lots o' lots o' lots o' changes!!!!
arch/mips/isa/formats.isa:
    include cop0.isa
arch/mips/isa/formats/basic.isa:
    fix faults
arch/mips/isa/formats/branch.isa:
arch/mips/isa/formats/fp.isa:
arch/mips/isa/formats/int.isa:
arch/mips/isa/formats/mem.isa:
arch/mips/isa/formats/noop.isa:
arch/mips/isa/formats/trap.isa:
arch/mips/isa/formats/unimp.isa:
arch/mips/isa/formats/unknown.isa:
arch/mips/isa/formats/util.isa:
arch/mips/isa/operands.isa:
arch/mips/isa_traits.cc:
arch/mips/linux_process.cc:
    merge MIPS-specific comilable/buidable files code into multiarch
arch/mips/isa_traits.hh:
    merge MIPS-specific comilable/buidable files code into multiarch... the miscRegs file accesses i have
    need to be recoded and everything should build then ...
arch/mips/stacktrace.hh:
    file copied over
