Implement a new m5exit instruction with an optional delay
arch/alpha/isa_desc:
move m5exit to m5exit old. The old version of the
instruction is now deprecated
Implement the new exit instruction with the optional delay
sim/sim_events.cc:
sim/sim_events.hh:
Make SimExit take a cycle
sim/universe.cc:
provide ticksPerMS, ticksPerUS, and ticksPerNS so we don't
have to do math during the cycle
