Gabe Black 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.

Gabe Black 05c86ec0d7 Get X86 to load an elf and start a process for it.
src/arch/x86/SConscript:
    Add in process source files.
src/arch/x86/isa_traits.hh:
    Replace magic constant numbers with the x86 register names.
src/arch/x86/miscregfile.cc:
    Make clear the miscreg file succeed. There aren't any misc regs, so clearing them is very easy.
src/arch/x86/process.hh:
    An X86 process class.
src/base/loader/elf_object.cc:
    Add in code to recognize x86 as an architecture.
src/base/traceflags.py:
    Add an x86 traceflag
src/sim/process.cc:
    Add in code to create an x86 process.
src/arch/x86/intregs.hh:
    A file which declares names for the integer register indices.
src/arch/x86/linux/linux.cc:
src/arch/x86/linux/linux.hh:
    A very simple translation of SPARC's linux.cc and linux.hh. It's probably not correct for x86, but it might not be correct for SPARC either.
src/arch/x86/linux/process.cc:
src/arch/x86/linux/process.hh:
    An x86 linux process. The syscall table is split out into it's own file.
src/arch/x86/linux/syscalls.cc:
    The x86 Linux syscall table and the uname function.
src/arch/x86/process.cc:
    The x86 process base class.
tests/test-progs/hello/bin/x86/linux/hello:
    An x86 hello world test binary.

Gabe Black 0150515ac3 Filled in with basic x86 information. Some things are missing, wrong, or non-sensical in x86.
