c4004482a5 Make "test" set some condition codes.
It still needs to zero the overflow and carry flags to be correct.

a68ddf685c Make memory instructions work better, add more macroop implementations, add an lea microop, move EmulEnv into it's own .cc and .hh.

d496492793 Make instructions that are illegal in 64 bit mode not do the wrong thing in 64 bit mode. Also add in more versions of PUSH and POP, and a version of near CALL.

056cfc345b Get rid of the commented out versions of macroops which have been reimplemented. The comments are basically functioning like a todo list.

6e286cddfa Get rid of the immediate and displacement components of the EmulEnv struct and use them directly out of the instruction. The extra copies are conceptually realistic but are just innefficient as implemented. Also don't use the zeroeth microcode register for general storage since it's now the zero register, and implement a load and a store microops.

8bd213b3b8 Move the microcode assembly to a python package instead of isa_parser files. Also, the code is now a single string which runs through the microcode assembler rather than docstrings associated with classes named after each architectural level instruction.
