ELF Loader: Use physical addresses instead of virtual ones.
...
This works in SE mode because the virtual and physical addresses specified for
segments are the same. In Alpha, the LoadAddrMask is still necessary because
the virtual and physical addresses are the same and apparently rely on the
super page mechanism. All of the regressions pass.

SPARC: Make nops have the IsNop flag set.
...
In O3, a nop is used to carry faults down the pipeline that didn't originate
from an instruction. If the instruction doesn't do anything, that is just
returns NoFault, but doesn't have IsNop set, the NoFault will overwrite the
fault that's being sent down and nothing will happen.

SPARC: Move tlb state into the tlb.
...
Each "strand" may need to have a private copy of this state, but I couldn't
find anywhere in the spec that said that after looking briefly.
This prevents writes to the thread context in o3 which was causing the
pipeline to be flushed and stopping any forward progress. The other ASI
accessible state will probably need to be accessed differently if/when we get
O3 full system up and running.

Move the argument files to src/sim and add a utility.cc file with a function
getArguments() that returns the given argument in the architecture specific fashion.
getArguments() was getArg() is the architecture specific Argument class and has had
all magic numbers replaced with meaningful constants. Also add a function to the

X86: Fix argument register indexing.
...
Code was assuming that all argument registers followed in order from ArgumentReg0. There is now an ArgumentReg array which is indexed to find the right index. There is a constant, NumArgumentRegs, which can be used to protect against using an invalid ArgumentReg.

X86: Fix carry calculation for subtraction based microops.

The carry flag should be calculated using the -complement- of the second operand, not it's negation. The carry in which is part of computing the 2's complement may induce a carry, but if you've already caused the carry before you get the carry computing logic involved, it will miss it.

- L2 can now receive ReadExReq from L1 since L1s have coherence

override it

Make an inner loop which pulls microops out of macroops. These aren't checked for control flow because we can pull out microops until we run out of buffer. This prevents microops from being interpretted as branches because the pc doesn't become npc.

Add support for microcode and pull out the special branch delay slot handling. Branch delay slots need to be squash on a mispredict as well because the nnpc they saw was incorrect.

Remove most of the special handling for delay slots since they have to be squashed anyway on a mispredict. This is because the NNPC value they saw when executing was incorrect.

Completely re-work how the scons framework incorporates swig
...
and python code into m5 to allow swig an python code to
easily added by any SConscript instead of just the one in
src/python. This provides SwigSource and PySource for
adding new files to m5 (similar to Source for C++). Also
provides SimObject for including files that contain SimObject
information and build the m5.objects __init__.py file.

Don't allow Source to accept multiple arguments, lists,
...
or automatically do Split(). It isn't used anywhere, and
isn't very consistent with the python features that are
about to be added. Do accept SCons.Node.FS.File arguments
though.

Fix NextEthernetAddr.
...
unproxy() needs to return a new object otherwise all
instances will use the same value. This fix is more
or less unique to NextEthernetAddr because its use of
the proxy stuff is a bit different than everything else.
