1926faac06 Add in support for LL/SC in the O3 CPU. Needs to be fully tested.
src/cpu/base_dyn_inst.hh:
    Extend BaseDynInst a little bit so it can be use as a TC as well (specifically for ll/sc code).
src/cpu/base_dyn_inst_impl.hh:
    Add variable to track if the result of the instruction should be recorded.
src/cpu/o3/alpha/cpu_impl.hh:
    Clear lock flag upon hwrei.
src/cpu/o3/lsq_unit.hh:
    Use ISA specified handling of locked reads.
src/cpu/o3/lsq_unit_impl.hh:
    Use ISA specified handling of locked writes.

a50e83c134 Fix assertion. I haven't tested it fully (I can't reproduce Lisa's error) but I believe it should fix what she's running into (which was definitely a bug).
src/cpu/o3/fetch_impl.hh:
    Move assertion to area where it should really always be true.  Sometimes you might recvRetry and not necessarily be blocked (if there was a squash).

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... )
