X86: Start implementing segmentation support.
...
Make instructions observe segment prefixes, default segment rules, segment
base addresses.
Also fix some microcode and add sib and riprel "keywords" to the x86
specialization of the microassembler.

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

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.

Get rid of some debug output and let macroops set headers in their constructor. The intention is to allow them to modify the emulation environment struct before it's used to construct its microops.

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.
