Fixes for SPARC_FS

configs/common/FSConfig.py:
    Make a SPARC system create an IO bus.
src/python/m5/objects/T1000.py:
    Create a T1000 platform
src/arch/sparc/miscregfile.cc:
    Initialize the strand status register to the value legion provides.
src/cpu/exetrace.cc:
    Truncate an ExtMachInst to a MachInst before comparing with Legion.
