Get SPARC to the point that it starts running. Add ability to load the ROM bin files, cleanup lockstep printing a bit

Since we don't have a platform yet, you need to comment out the default responder stuff in Bus.py to make it work.

SConstruct:
    Add TARGET_ISA to the list of environment variables that end up in the build_env for python
configs/common/FSConfig.py:
    add a simple SPARC system to being testing with, you'll need to change makeLinuxAlphaSystem to makeSparcSystem in fs.py for now
src/SConscript:
    add a raw file object, at least until we get more info about how to compile openboot properly
src/arch/sparc/system.cc:
src/arch/sparc/system.hh:
    add parameters for ROM files (OBP/Reset/Hypervisor), a ROM, load files into ROM
src/base/loader/object_file.cc:
src/base/loader/object_file.hh:
    add option to try raw when nothing works
src/cpu/exetrace.cc:
    cleanup lockstep printing a little bit
src/cpu/m5legion_interface.h:
    change the instruction to be 32 bits because it is
src/mem/physical.cc:
    fix assert that doesn't work if memory starts somewhere above 0
src/python/m5/objects/BaseCPU.py:
    Add if statement to choose between sparc tlbs and alpha tlbs
src/python/m5/objects/System.py:
    Add a sparc system that sets the rom addresses correctly
src/python/m5/params.py:
    add the ability to add Addr() together
