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.

4b29d22386 X86: Get rid of initialization of R11 
R11 is just junk after the start of exectuion because we're "returning" from
an execve call and linux destroys the contents of rcx and r11 on system calls.

55ade789d3 X86: Add operand type information to the fnstcw and fldw instruction placeholders. 
These are the only floating point instructions that get used in my simple hello world test. These instructions are for setting up the floating point control register. Their not being implemented doesn't affect anything because floating point isn't used.

2f93db6f95 memory system: fix functional access bug. 
Make sure not to keep processing functional accesses
after they've been responded to.
Also use checkFunctional() return value instead of checking
packet command field where possible, mostly just for consistency.

b4087e0e44 Statetrace: Make statetrace patch amd64 executables for true single stepping after system calls. 
Because of peculiarities in how system calls are returned from, single stepping executes some system calls and the instruction following them in a single step. Statetrace now patches the executable image when it detects a system call to force "correct" behavior, aka the appearance of stepping one instruction every single time.
