Finally MIPS does hello world!

arch/mips/isa/bitfields.isa:
    add RS_SRL bitfield ...these must be set to 0 for a SRL instruction
arch/mips/isa/decoder.isa:
    Make unimplemented instructions Fail instead of just Warn
    Edits to SRA & SRAV instructions
    Implement CFC1 instructions
    Unaligned Memory Access Support (Maybe Not fully functional yet)
    Enforce a more strict decode policy (in terms of different bitfields set to 0 on certain instructions)
arch/mips/isa/formats/branch.isa:
    Fix disassembly
arch/mips/isa/formats/int.isa:
    Add sign extend Immediate and zero extend Immediate to Int class.
    Probably a bit unnecessary in the long run since these manipulations could
    be done in the actually instruction instead of keep a int value
arch/mips/isa/formats/mem.isa:
    Comment/Remove out split-memory access code... revisit this after SimpleCPU works
arch/mips/isa/formats/unimp.isa:
    Add inst2string function to Unimplemented panic. PRints out the instruction
    binary to help in debuggin
arch/mips/isa/formats/unknown.isa:
    define inst2string function , use in unknown disassembly and panic function
arch/mips/isa/operands.isa:
    Make "Mem" default to a unsigned word since this is MIPS32
arch/mips/isa_traits.hh:
    change return values to 32 instead of 64
arch/mips/linux_process.cc:
    assign some syscalls to the right functions
cpu/static_inst.hh:
    more debug functions for MIPS (these will be move to the mips directory soon)
mem/page_table.cc:
mem/page_table.hh:
    toward a better implementation for unaligned memory access
mem/request.hh:
    NO ALIGN FAULT flag added to support unaligned memory access
sim/syscall_emul.cc:
    additional SyscallVerbose comments
