MIPS ISA runs 'hello world' in O3CPU ...

src/arch/mips/isa/base.isa:
    special case syscall disasembly... maybe give own instruction class?
src/arch/mips/isa/decoder.isa:
    add 'IsSerializeAfter' flag for syscall
src/cpu/o3/commit.hh:
    Add skidBuffer to commit
src/cpu/o3/commit_impl.hh:
    Use skidbuffer in MIPS ISA
src/cpu/o3/fetch_impl.hh:
    Print name out when there is a fault
src/cpu/o3/mips/cpu_impl.hh:
    change comment
