Steve Reinhardt 0e79d188e1 Hacks to avoid compiling in old FullCPU model.
Needed in the interim until we port the old model over
to the new interface.  Long term we should have a cleaner
solution for controlling which models get compiled in.

SConscript:
    Move old FullCPU source file list to separate full_cpu_sources
    list so we can choose to not include it in compile.
arch/isa_parser.py:
    Hack to avoid generating FullCPU execute files.
    Need a better way to control this.
cpu/exetrace.cc:
    Don't include old FullCPU-specific headers (apparently
    unnecessary anyway--or if not they should be).
