19ca97af79 This changeset gets the MIPS ISA pretty much working in the O3CPU. It builds, runs, and gets very very close to completing the hello world
succesfully but there are some minor quirks to iron out. Who would've known a DELAY SLOT introduces that much complexity?! arrgh!

Anyways, a lot of this stuff had to do with my project at MIPS and me needing to know how I was going to get this working for the MIPS
ISA. So I figured I would try to touch it up and throw it in here (I hate to introduce non-completely working components... )

src/arch/alpha/isa/mem.isa:
    spacing
src/arch/mips/faults.cc:
src/arch/mips/faults.hh:
    Gabe really authored this

    add StoreConditional Flag to instruction

    Steven really did this file
src/arch/mips/isa/formats/branch.isa:
    fix bug for uncond/cond control

e60f998e29 Had to add this because for some reason gcc wasnt recognizing "THE_ISA == ALPHA_ISA"... wierd but OK

03fa13b27c Use O3DynInst in cpu_models.py and in static_inst_exec_sigs.hh instead of a specific ISA dyn. inst.
src/cpu/cpu_models.py:
    Use O3DynInst
src/cpu/o3/dyn_inst.hh:
    declare O3DynInst here based off of ISA ... this must be updated for each ISA.
src/cpu/static_inst.hh:
    take out O3 forward declarations here and include header file to keep this file clean
