Nathan Binkert 15613161c2 Commit a command for use inside a simulated system for communicating
with the simulator.  This program is generally compiled as the name
m5 and installed in /usr/local/bin

This command uses opcodes that are invalid on a normal system, so
don't expect it to do anything on a real system.
