copyRegs and copyMiscRegs were moved to utility.hh and utility.cc.

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.

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.
