infinitesimal small baby steps toward MIPS actually working

arch/mips/isa/formats/branch.isa:
    let user know that we alter r31 in disassembly
arch/mips/isa_traits.cc:
    add copyRegs function ...
    comment out serialize float code for now
arch/mips/isa_traits.hh:
    make FloatRegFile a class ... change values of architectural regs
arch/mips/process.cc:
    change MIPS to Mips
base/loader/elf_object.cc:
    get global pointer initialized to a value
base/loader/elf_object.hh:
    Add global_ptr to elf_object constructor
base/loader/object_file.hh:
    MIPS to Mips
base/traceflags.py:
    SimpleCPU trace flag
cpu/simple/cpu.cc:
    DPRINTF flags for SimpleCPU
cpu/static_inst.hh:
    Add Decoder functions to static_inst.hh
