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 --HG-- extra : convert_revision : e2ed47a2e5cfcd57c82086c6fcb4a28bf801c214
