Check in of new CPU. This checkin works under non-Fullsystem mode, with no caches.

SConscript:
    Added new CPU files to build.
arch/alpha/isa_desc:
    Changed rduniq and wruniq to be nonspeculative because the uniq register is not renamed.
arch/isa_parser.py:
    Added new CPU exec method.
base/statistics.hh:
    Minor change for namespace conflict.  Probably can change back one the new CPU files are cleaned up.
base/traceflags.py:
    Added new CPU trace flags.
cpu/static_inst.hh:
    Changed static inst to use a file that defines the execute functions.
