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.

c0670187c5 X86: Add functions to read and write to an exec context. 
These functions take care of calling the thread contexts read and write functions with the right sized data type, and handle unaligned accesses.

57428b8b0b 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.

abc76f20cb Major changes to how SimObjects are created and initialized. Almost all 
creation and initialization now happens in python.  Parameter objects
are generated and initialized by python.  The .ini file is now solely for
debugging purposes and is not used in construction of the objects in any
way.
