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.
