e524240d68 Make disassembled x86 register indices reflect their size. 
This doesn't handle high byte register accesses. It also highlights the fact that address size isn't actually being calculated, and that the size a microop uses needs to be overridable from the microassembly.

a6757095c3 Add in support for condition code flags. 
Some microops can set the condition codes, and some of them can be predicated on them. Some of the codes aren't implemented because it was unclear from the AMD patent what they actually did. They are used with string instructions, but they use variables IP, DTF, and SSTF which don't appear to be documented.

a7f3bbcfab Make microOp vs microop and macroOp vs macroop capitilization consistent. 
src/arch/x86/isa/macroop.isa:
    Make microOp vs microop and macroOp vs macroop capitilization consistent. Also fill out the emulation environment handling a little more, and use an object to pass around output code.
src/arch/x86/isa/microops/base.isa:
    Make microOp vs microop and macroOp vs macroop capitilization consistent. Also adjust python to C++ bool translation.
