9b49a78cfd Address translation: Make the page table more flexible.
The page table now stores actual page table entries. It is still a templated
class here, but this will be corrected in the near future.

fae60c164e Arguments: Get rid of duplicate code for the Arguments class in each architecture.
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
Argument class for testing if an argument is NULL.

239d124e83 MIPS: Cleaned up includes to break loops, and got rid of isa_traits.cc
Loops of header files including each other was causing compilation to fail. To fix it, a bunch of unnecessary includes were removed, and the code in isa_traits.cc which brought a bunch of include chains together was broken up and put in proximity to the header files that delcared it.

d1e533a1e2 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.

ea70e6d6da Make branches work by repopulating the predecoder every time through. This is probably fine as far as the predecoder goes, but the simple cpu might want to not refetch something it already has. That reintroduces the self modifying code problem though.

1aef5c06a3 Rework the way SCons recurses into subdirectories, making it
automatic.  The point is that now a subdirectory can be added
to the build process just by creating a SConscript file in it.
The process has two passes.  On the first pass, all subdirs
of the root of the tree are searched for SConsopts files.
These files contain any command line options that ought to be
added for a particular subdirectory.  On the second pass,
all subdirs of the src directory are searched for SConscript
files.  These files describe how to build any given subdirectory.
I have added a Source() function.  Any file (relative to the
directory in which the SConscript resides) passed to that
function is added to the build.  Clean up everything to take
advantage of Source().
function is added to the list of files to be built.
