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.

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.

c59f9456b9 Fix up the base x86 fault object and create a fault to be generated by unimplemented instructions in their microcode. This is useful if certain variations of an instruction are implemented, but, for instance, it's memory based versions aren't.

ff7b89beee The process of going from an instruction definition to an instruction to be returned by the decoder has been fleshed out more. The following steps describe how an instruction implementation becomes a StaticInst.
1. Microops are created. These are StaticInsts use templates to provide a basic form of polymorphism without having to make the microassembler smarter.
2. An instruction class is created which has a "templated" microcode program as it's docstring. The template parameters are refernced with ^ following by a number.
3. An instruction in the decoder references an instruction template using it's mnemonic. The parameters to it's format end up replacing the placeholders. These parameters describe a source for an operand which could be memory, a register, or an immediate. It it's a register, the register index is used. If it's memory, eventually a load/store will be pre/postpended to the instruction template and it's destination register will be used in place of the ^. If it's an immediate, the immediate is used. Some operand types, specifically those that come from the ModRM byte, need to be decoded further into memory vs. register versions. This is accomplished by making the decode_block text for these instructions another case statement based off ModRM.
4. Once all of the template parameters have been handled, the instruction goes throw the microcode assembler which resolves labels and creates a list of python op objects. If an operand is a register, it uses a % prefix, an immediate uses $, and a label uses @. If the operand is just letters, numbers, and underscores, it can appear immediately after the prefix. If it's not, it can be encolsed in non nested {}s.
5. If there is a single "op" object (which corresponds to a single microop) the decoder is set up to return it directly. If not, a macroop wrapper is created around it.

In the future, I'm considering seperating the operand type specialization from the template substitution step. A problem this introduces is that either the template arguments need to be kept around for the specialization step, or they need to be re-extracted. Re-extraction might be the way to go so that the operand formats can be coded directly into the micro assembler template without having to pass them in as parameters. I don't know if that's actually useful, though.

4285990a96 Reworking how x86's isa description works. I'm adopting the following definitions to make figuring out what's what a little easier:
MicroOp: A single operation actually implemented in hardware.
MacroOp: A collection of microops which are executed as a unit.
Instruction: An architected instruction which can be implemented with a macroop or a microop.

7fcc9d2106 Made the MultiOp format do a little more. It now sets up single microop instructions to return an instance of the right class. The code to decode register numbers and generate loads and stores still needs to be added. Also, a syntax for specifying operands as sources, destinations, or both needs to be established. Multipl microop instructions are also not handled, pending real macroop generation support.

e67a207ad3 Add a microcode assembler. A microcode "program" is a series of statements. Each statement has an optional label at the beginning, a capitilized microcode class name which is roughly equivalent to a mnemonic in a regular ISA, and then an optional series of operands seperated by white space. The operands are either a decimal constant, a label, or a code fragment surrounded by non nested {}s. Labels are a letter or underscore followed by letters, underscores, or digits. The syntax for describing code segments might need to be changed if a need arrises to have {}s in the code itself.

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.
